The honeymoon continued for Keira Knightley and her new husband, James Righton, in Corsica today. Keira wore a bikini for a dip in the ocean, though she's showed off other looks with her laid-back honeymoon style, which has even included wearing the same dress three different ways! For her dressed-down swim, she was joined by shirtless James, who showered her with kisses in the water. They've been all about the sweet PDA during their romantic getaway and showed similar affection while enjoying lunch and strolling the beach last week.

Keira and James jetted off to France after tying the knot on May 4. They were wed at the town hall in Mazan and celebrated after the ceremony with friends and family at a reception held at her parents' farmhouse.

It was an extraspecial weekend for Anna Paquin and her family since it was her first time celebrating Mother's Day! They got a head start on the fun on Saturday, when they met up with friends for a party at a Malibu park. Anna and her husband, Stephen Moyer, took turns holding onto their boy and girl twins, whose names have not been revealed, and mingling with guests. The babies were born in September and since then have joined their parents for shopping trips and strolls along Venice Beach, though their sweet faces have been kept mostly under wraps. It hasn't been all about parenthood for Anna and Stephen, though, since they've also been working on the sixth season of True Blood. The series doesn't return until June 16, but you can check out pictures from True Blood season six now to gear up for the next installment!

Hilary Duff escaped to Mexico with her family over the weekend to celebrate Mother's Day. She had husband Mike Comrie, son Luca, and sister Haylie along for the celebratory trip, which she recognized on Twitter, writing, "Feel so very lucky to be a mother today! And everyday! Happy Mother's Day to all the mothers out there, it can be a hard job but the best! Good work!" Hilary also shared her thoughts on motherhood with People recently, adding that, "I think asking for help on a tired day isn't a sign of weakness. A lot of changes have come into your life quickly and it's important to take time for yourself!"

Hilary wore a bikini during the sunny days, which included hanging out poolside, hitting the beach, and kicking a ball around the grass. Hilary is just one of the many famous moms who celebrated Mother's Day in a special way including Jessica Alba, who went out to brunch with her family of four.

Robert Pattinson and Kristen Stewart checked out of their NYC hotel, hopped into a waiting car, and headed to JFK to catch a flight Wednesday. They didn't go straight to the airport, though — their driver stopped en route to pick them up a few slices of pizza!

Although they were both in the Big Apple, Kristen attended the Met Gala on Monday night without Rob by her side. He missed out on a fun evening with friends since Tom Sturridge and Sienna Miller were also at the bash and ended up leaving with Kristen. They weren't the only famous pals that Kristen spent time with — she arrived with Cameron Diaz and Stella McCartney! Both Kristen and Cameron were decked out in looks by the designer, with Kristen in a lace-embroidered jumpsuit and Cameron in a cobalt-blue caped dress.

The NYC visit wasn't all about the red carpet for Kristen, since she reportedly also checked out a performance of Orphans, which Tom stars in, on Broadway. Rob was also rumored to have been in the audience during a recent, but separate, showing.

Gwyneth wore a pink Valentino gown for the annual fashion event, which she attended with her husband, Chris Martin.

During the chat, Gwyneth also joked that the highlight of her Met Gala night was "going home and taking my shoes off" and spoke about her love for public transportation. Gwyneth said she "rides the subway in London all the time" but that "the last time I rode the subway in New York was a year-and-a-half ago."

Zac kissed a costar during one rowdy take last month and has also sported a bathrobe and other costumes for the cameras.

Tom, on the other hand, went with a bright blue number fresh off his big Kentucky Derby win.

Gisele chose a daring look from designer Anthony Vaccarello for the event, which celebrated the Punk: Chaos to Couture exhibit at the Metropolitan Museum of Art.

On Saturday, Gisele, Ben, and Vivian met up with Tom and Jack for dinner at Blue Ribbon.

Kim Kardashian and Kanye West made a grand entrance to NYC's Metropolitan Museum of Art for last night's Costume Institute Benefit.

The couple, who are expecting their first child in July, attended the gala together for the first time, since Kanye was the live entertainment for the event. Although Kim was scrutinized for her covered-up look, Kanye came to her defense during his performance last night on stage adding a line into his song directed at Kim singing, "You're so awesome." His sentiments were reflected on the red carpet as well as Kim and Kanye shared many affectionate moments on their way into the fashionable affair. Click through to see them all!

The annual Costume Institute Benefit is all about fashion and fun, but before the stars can celebrate inside the bash, they have to make their way into the Metropolitan Museum of Art by way of the grand staircase.

Jennifer shared a moment with fellow face of Dior Marion Cotillard as well as Sarah Jessica Parker on the carpet. On her way in, Jennifer stopped to chat about the decision-making process, which she says is pretty easy when you have the designer of Dior Couture giving you direction.
