Alexa Chung, Olga Kurylenko, and Marion Cotillard are the latest in a long list of fashion darlings and actresses to take Raf Simons from the runway to the red carpet. Ever since Belgian designer Simons, formerly of Jil Sander, took the reins at the legendary label, he's presented five exquisite collections. Naturally, stars like Cotillard (the face of Lady Dior) and Jennifer Lawrence (the face of Miss Dior handbags) have flocked to his jaw-dropping gowns, and we can totally see why. Simons is breathing new life into the design house by taking iconic past-collection references (think New Look from the 1940s) and updating them with a modern twist. Step inside to see all the stars who have donned Simons's designs for Dior now.

It's been a fun-filled week in la-la land, with many celebrities heading to Coachella last weekend to catch some of the many musical acts performing this year. Robert Pattinson took charge and led his girlfriend Kristen Stewart through the busy crowd, while Diane Kruger and her beau Josh Jackson couldn't keep their hands off each other. Miranda Kerr jetted into Sydney to model the new Qantas uniforms, and hung out with John Travolta at the Gala Dinner a few days later, while Rebel Wilson did Australia proud as the host of the MTV Movie Awards. Of course, no one was immune to the tragic Boston bombings early in the week — and Bradley Cooper paid a visit to a very special survivor on April 19. There was plenty more action to see, so click through to check it all out!

Rachel Bilson and Hayden Christensen continued their Barbados vacation with friends today. Rachel slipped into a skimpy striped bikini and took time to snap pictures of her friend with a small monkey while laughing in and out of the water. After playing photographer, Rachel sprinted down the beach to catch up with Hayden and share a few words before heading along the shore together.

Their Caribbean fun started Saturday, when Rachel and Hayden, who are going strong since calling off their engagement back in 2010, showed plenty of PDA during another beach session. Rachel is soaking up the sun during a mid-season break from filming her show Hart of Dixie, which will air its newest episode tonight in the US on the CW network.

Marion Cotillard is the latest — and possibly the most loyal — in a long list of fashion darlings and actresses to take Raf Simons from the runway to the red carpet. Ever since Belgian designer Raf Simons, formerly of Jil Sander, took the reins at the legendary label, he's presented four exquisite collections, with one more on its way this week. Naturally, stars like Cotillard (the face of Lady Dior) and Jennifer Lawrence (the face of Miss Dior handbags) have flocked to his jaw-dropping gowns, and we can totally see why. Simons is breathing new life into the design house by taking iconic past-collection references (think New Look from the 1940s) and updating them with a modern twist.

We could rename this the week of the Little Black Dress, after we spied numerous style-setters stepping out in the the classic wardrobe piece. Diane Kruger's sheer-panelled Thakoon number was pure perfection — classy, with a hint of sex appeal thrown in for good measure — and those silver shoes! We couldn't get enough. Also in LBDs? Megan Gale, in form-fitting leather and Rachel Bilson, who went with a rainbow twist on the classic. Then there was Jessica Alba in some of the coolest pants we've seen, visiting model Barbara Palvin in a feminine white sheath, one model in a very popular jumpsuit and more. It's all in here, click through to see it all!

Rosie Huntington-Whiteley met up with her Transformers: Dark of the Moon co-star Josh Duhamel at the launch of BlackBerry's new Z10 phone in LA last night. Other celebrity attendees included Rachel Bilson, Chloë Moretz and Christina Ricci, who chatted with Rosie on a banquette.

Josh has a big weekend ahead of him as he'll be hosting the Kids' Choice Awards this weekend. He'll also have plenty to do in the coming months as he and wife Fergie prep for the arrival of their first child. Fergie is currently in NYC, where she made an appearance on Good Morning America today and shared that she is still trying to adjust to pregnancy. Fergie said, "I have no idea what I'm doing. I'm just going to play it by ear and see how things go, and let the natural instincts kick in."
