Heather Graham

It's the warm season over in the US right now, so all our favourite stars are busy putting their best Summer beauty looks forward. Rachel Bilson left her face clean, clear and bronzed, letting her chocolate-drop, kohl-lined eyes do all the talking, while Blake Lively's look was equally relaxed, this time in the hair department. Selena Gomez rocked a matte red lip and perfect beach waves, while one star's polished top knot has us yearning for an appropriate event to try it out at. But the winner? It's gotta be Rose Byrne. The hair, the skin, the eyes. . . This Aussie lady's got it all, and we couldn't love it more. Click through to see it all!

Fresh from their Paris premiere of The Hangover Part III last night, the stars of the movie boarded a plane to Brazil and went straight to the beach! Heather Graham showed off her fit physique in a patterned bikini in Rio de Janeiro and played around with Ken Jeong in the water. On another part of the beach, the Wolfpack stripped down — Ed Helms and Zach Galifianakis wore bright trunks — but Bradley Cooper kept his shirt on. Hours later the stars were back on the red carpet for yet another premiere.

Bradley Cooper, Justin Bartha, Zach Galifianakis and a Talbot Runhof-clad Heather Graham got friendly with fans at the Paris premiere of The Hangover Part III last night. Ed Helms also joined his crew for the red carpet fun, snapping pictures and signing autographs on his way into the screening. It was a special night for Justin, who was accompanied by his new fiancée, Lia Smith, for the fun in France as well.

Although the cast will be parting ways as they wrap up their tour for the final film of their Hangover trilogy, the boys and Heather have gotten in some quality time on their current promotional trail. The crew debuted the film in LA last Monday and they partied it up in London after the UK premiere on Thursday night. The Hangover gang still appeared happy to celebrate the film in France last night, despite the movie's US box office loss to Fast & Furious 6 over the weekend.

London got a large dose of star power on Wednesday when the cast of The Hangover hit the red carpet to premiere the third instalment of their franchise. Bradley Cooper, Justin Bartha, Ed Helms, Zach Galifianakis, Todd Phillips, Ken Jeong and Heather Graham met up in front of the cameras to pose for pictures and chat among themselves, flashing plenty of smiles along the way. It was their second big event of the week after also bringing the movie to LA on Monday. It looked like Zach was on his best behaviour in the UK following his funny antics at the West Coast premiere — Zach hopped into a car trunk before walking the carpet with his formerly homeless friend, Mimi Haist.

It was a wild reunion for the cast of The Hangover at the premiere of the franchise's third instalment in LA today. Bradley Cooper broke from the NYC set of American Hustle to attend the big event alongside Ed Helms and Zach Galifianakis. The trio showed love for their co-star Ken Jeong and the waiting fans, many of whom Bradley stopped to snap pictures with before heading into the screening. The ladies of the Hangover trilogy, including Heather Graham, Sasha Barrese, Gillian Vigman and Jamie Chung all hit the red carpet as well to celebrate the film's release, which is out in Australia on May 23.

Yoga may be an ancient practice, but it feels like we're constantly hearing a new celebrity boasting about its impact.

Today's CFDA Awards drew an impressive crowd mixed with models, actors, fashion designers and industry heavyweights alike. Mary-Kate Olsen stood out from the fashion pack — and her sister — with shiny new brown locks, while Mandy Moore, Joan Smalls, Busy Philipps and Kate Bosworth jumped on the pink lip brigade with different interpretations of the candy-hued trend. Step inside our gallery for a closer look (with zoom and all!).

Rachel Zoe and her husband Rodger Berman were among the celebrities who turned out for Monday night's Los Angeles Gay and Lesbian Center benefit at Sunset Tower. Mandy Moore, in Lela Rose, also posed on the black carpet, and inside, Rachel made the rounds with her good friend, and client, Anne Hathaway, as well as former San Francisco mayor Gavin Newsom. Anne presented the first annual Visionary Award to Rachel, and the two ladies laughed and shared a hug onstage. The presentation was followed by a silent auction held to raise funds for the organisation's homeless youth services. Rachel tweeted afterward that it had been "The most amazing night surrounded by the most amazing friends." There was another reason for Rachel to celebrate — she just crossed the one million Twitter followers mark!

What do two of your favourite Twilight stars have in common? Polish-free toenails, that's what! Being someone who is (truly, madly, deeply) in love with nail polish, it came as quite a surprise to see many of our Bella faves opting to go sans nail polish on their toes, particularly to red carpet events.
