Ashley Greene and Vanessa Hudgens showed off their bikini bodies — and athleticism — at Oakley's Learn to Ride event in Bali, Indonesia, today. The ladies both hopped on surfboards to catch a few waves at the event, which serves to promote the sport of surfing. Ashley and Vanessa were sharing the perfect conditions with pro surfers since the event coincided with Oakley's Pro Bali surf competition as well. Although Ashley was able to successfully ride the waves, she did not escape the day without injury. She shared a picture of her leg, which was covered in scrapes, on her Twitter account, writing, "War wound from surfing today with Oakley. The reef ate me up." While Ashley and Vanessa were enthusiastic to try their hand at the water sport, the girls did find time to relax and soak in the Indonesian rays on a boat during the day as well.

Miley Cyrus held on to her fiancé, Liam Hemsworth, for a movie date at ArcLight Cinemas in LA on Monday. The couple's night out marked the first time they have made a public appearance together since their trip to Costa Rica back in January. Miley wore her engagement ring for the date night, which may put to rest months of speculation surrounding their rocky relationship. While all seems to be well with Miley and Liam, the same cannot be said for Miley's parents, Billy Ray and Tish Cyrus, who recently announced they are divorcing after 19 years of marriage.

Miley and Liam's night out preceded a big day for her since she released her new music video for "We Can't Stop" today. Along with stirring controversy over the risqué video, Miley made headlines for her recent interview with Rolling Stone, in which she addressed her "stoner" reputation. When speaking out about her mentality toward marijuana, Miley revealed, "I think alcohol is way more dangerous than marijuana — people can be mad at me for saying that, but I don't care. I've seen a lot of people spiral down with alcohol, but I've never seen that happen with weed."

Kris Jenner joined her daughters Khloé Kardashian and Kourtney Kardashian for a frozen yogurt stop in LA yesterday. The trio were all smiles for the outing, which came after the news that Kim Kardashian gave birth to her first child, a baby girl, in LA over the weekend. Kim and Kanye are reportedly still deliberating over the baby's name, but she did reveal that she is enjoying motherhood to pal Ryan Seacrest.

Kim's friends and family have been sharing details about the new baby. Proud aunt Khloé took to Twitter on Sunday to announce her happiness, while Kim's mom, Kris, gushed about her new granddaughter to reporters at the Daytime Emmys later that day, saying, "We are all good and extremely happy and thrilled for the new baby. [The baby] is doing great and beautiful. So very exciting." Kim's family members were not the only ones to spread the love, since the couple's friend Beyoncé Knowles publicly congratulated Kim and Kanye on her personal website.

Miranda Kerr spent a sunny morning with her son, Flynn Bloom, in NYC today. It looks like Flynn may be taking tips from his model mom as he showed his big smile for the cameras during their stroll. The duo were out in the Big Apple following her whirlwind trip to South Korea last week. On Wednesday, Miranda made a promotional stop at a department store in Seoul, and on Thursday she showed off her athleticism by throwing out an honorary pitch during a baseball game.

Miranda and Flynn will have a bit of bonding time to spend together in the Big Apple since Orlando Bloom will be busy with his new Broadway gig. Orlando is set to make his Broadway debut this Fall in Romeo and Juliet, which begins previews on Aug. 24. Along with his stage duties, he'll also be hitting big screens in the next Hobbit installment — check out the new trailer for The Hobbit: The Desolation of Smaug!

Reese Witherspoon had the company of her brother, John, for a trip to the pool with her son Deacon in Nashville yesterday. Deacon beat the Southern heat with a dip while he accompanied his mom in her native Tennessee for family time. Reese, Deacon, and her oldest child, Ava, caught a flight out of LAX on Saturday together, but they were without her husband, Jim Toth, or Reese's ex Ryan Phillippe ahead of Father's Day.

Ryan may not have been able to spend the holiday with his children since he was in Hawaii promoting his new project, Isolated, at the Maui Film Festival last week. He did have his kids on his mind, though, since Ryan spoke of steering them in a direction other than show business during an interview there. He said, "I don't mean to dismiss or demean our industry but I'd like to see them do something a little more meaningful or important [than enter show business]."

Harry Styles fit in serious shirtless time while in Miami recently. He stripped down to a pair of white shorts to hop on board a yacht with his One Direction bandmates in Florida on Saturday and also showed off his abs last week during a night out with his pal Niall Horan. Harry and Niall went shirtless after the sun went down, and the duo stopped to take pictures and greet fans as they departed their boat. The One Direction crew fit in fun in the sun between taking the stage in Ft. Lauderdale and Miami last week, though they've since moved onto Nashville where they are schedule to perform tomorrow.

While Harry's been showing skin in Miami, he chose a much more formal look for a special occasion earlier this month. Harry buttoned up in a tuxedo to serve as the best man at his mom Anne Cox's wedding in Cheshire, England, two weeks ago, joining the long list of celebrities taking part in wedding season.

Rosie Huntington-Whiteley donned a short Emilio Pucci dress to show her love and support for her beau, Jason Statham, at his Hummingbird premiere in London's Leicester Square last night.

Along with having Rosie by his side, Jason posed with his other leading lady of the evening, his costar Agata Buzek, as well as his director Steven Knight, who joined in on the festivities. The film follows the story of a homeless former special forces soldier who is forced into the criminal underworld in London while on the run from a military court martial.

Apart from last night's red carpet affair, Rosie and Jason were able to pack on the PDA recently during a bikini-filled getaway in the South of France earlier this month. Their romantic trip came on the heels of a busy time for the couple. Rosie made an appearance at the Cannes Film Festival in May, while Jason was tied up with work for his new project, Heat, as well as wrapping a promotional tour for Fast & Furious 6.

Tom Cruise went shirtless for his Father's Day celebrations in Malibu, where he joined his son, Connor Cruise, for a stand-up paddleboarding session. Tom wasn't the only famous dad to spend the day with his son — see how all the other stars celebrated Father's Day.

Tom's latest outing with Connor comes after they joined the Beckham family in the stands at an LA Kings playoff game late last month. Tom may have more time on his hands to dedicate to his kids since he recently dropped out of Warner Bro.'s Man From U.N.C.L.E., which is to be directed by Guy Ritchie. Man of Steel star Henry Cavill is reportedly in the running to replace him in the classic spy series film.

Courteney Cox's 49th birthday celebrations in LA over the weekend were a star-studded affair.

Courteney took to her Twitter account to document the fun surrounding the special occasion, which would not be complete without her daughter, Coco Arquette. She shared a photo of herself and her daughter during the party writing, "Every birthday is perfect with my favorite girl."

Busy sent her wishes on Twitter too writing, "Happy Birthday to Courteney Cox! One of the greatest ladies I know!"

Gisele Bündchen wore a sexy sheer top for the launch of her new lingerie line, Gisele Bündchen Intimates, in her native Brazil yesterday. Ahead of unveiling the collection at a mall in Sao Paulo, Gisele stripped down to model the looks herself, sharing photos on her social accounts earlier this month. Although she spent Sunday in Brazil working, she didn't forget about her husband, Tom Brady, on Father's Day. Gisele shared an adorable photo of Tom kissing their son, Ben, on Instagram, writing, "Thank you for being the most loving father in the world. Wish I could be with you today. Happy Father's Day." See how other stars celebrated Father's Day! While they spent the special occasion apart, Tom and Gisele have packed in many recent loving outings together as a family, including a PDA-filled park date with the kids earlier this month.

Brad Pitt sat among a group of cheering fans for an interview with Good Morning America's George Stephanopoulos this morning in NYC. Brad's promoting his new flick, World War Z, in the Big Apple ahead of its release in the US on Friday. He popped up on GMA this morning after making dozens of stops around the world for the zombie apocalypse film, most recently in South Korea and Australia, where his son Pax accompanied him on his travels. He'll be on the go again soon with his next World War Z appearance taking him back overseas to Russia.

Brad's fiancée, Angelina Jolie, has also shown her support for his latest film, joining him for the UK premiere earlier this month, where she made her first red carpet appearance since her double mastectomy news. She also celebrated her birthday in Berlin accompanied by all of their children during his promotional trail earlier this month. Along with chatting up the film, Brad spoke about Angelina during his interview this morning, explaining his heart-felt admiration for her and her decision to undergo the preventative surgeries. He said, "She's doing great. When she wrote her piece, we had already come out the other end and we're feeling really good about it. We're really surprised and moved by how many people are dealing with the same issue, or wondering about the same issue. Her idea was that if someone could learn from her story, then she would love to share that. But it's just been a beautiful thing to watch, and her focus now is that all people have access to the testing and know what they can do about it. And she has certainly shown if you do your research and make your decision, what's best for you, it doesn't have to be a scary thing."

It was a week filled with excitement for stars, between red carpets, award shows, and Summer siorees. Cameron Diaz and Naomi Watts stepped out to show their support for Stella McCartney at her Spring presentation garden party in NYC, while pregnant Kate Middleton made a stylish final public appearance before maternity leave to christen a Princess Cruises ship in the UK. Brad Pitt brought his son Pax along for a trip to South Korea, and Jennifer Aniston and Bradley Cooper reunited for a laugh backstage at the Guys Choice Awards in LA.
