Rihanna

This weekend, the UK got fully into festival season with not one but two big music events — the Isle of Wight and BBC Radio 1 Hackney Weekend. Singers from both sides of the Atlantic brought their best on-stage style to Newport and Hackney Marshes, with Jessie J and Lana Del Rey hot footing it from the island to East London to sing at both bashes. Jessie J made a statement with her trousers at each performance, donning seriously ripped jeans on the Isle of Wight then a monochrome striped pair at Hackney Weekend, while Lana bared her legs in a pair of denim hot pants and fringe tshirt then a red bubble skirt dress. Rihanna chose short shorts too as she took to the London stage on Saturday and Sunday, while Leona Lewis bared her midriff, Rita Ora was head-to-toe prints and Florence Welch went for a waterfall hem gown. Take a look at them all here and tell me who was most fab!

Brooklyn Decker, Rihanna, and Alexander Skarsgard hit the blue carpet in LA last night for the West Coast premiere of Battleship. The ladies headed west after a big start to the week in NYC, where they both attended Monday's Met Gala. Brooklyn wore Tory Burch to the Big Apple fashion fest, while Rihanna donned a crocodile-print Tom Ford.

Battleship isn't out until next Friday, but the gang have been all over the world doing press for the last month. Brooklyn, Alexander, and costar Taylor Kitsch brought the picture to Europe, then Rihanna linked up for a quick tour of Asia and a stop in Hawaii for the junket. Brooklyn's doing double-duty, too, since her What to Expect When You're Expecting comes out the same day as her movie with Alexander and Rihanna!

Rihanna joined her Battleship costars Alexander Skarsgard, Taylor Kitsch, and Brooklyn Decker, as well as director Peter Berg, at Friday's photocall for the film. The stars returned to Hawaii, where they shot the movie last Summer, for the US press junket. They posed in front of Pearl Harbor's USS Missouri Memorial with naval vet Gregory D. Gadson — stay tuned for our exclusive interviews with the cast!

Rihanna flashed her midriff for the photo op. She also shows skin in her new video, which is out today. "Where Have You Been" is already a hit on the charts, and with Rihanna in a bikini, the video is sure to be just as popular. Rihanna, Brooklyn, Alexander, and Taylor head back to the mainland next week and are expected to attend an LA premiere on May 10 before the May 18 opening.

Time magazine celebrated its 100 Most Influential People last night with a huge bash held inside Jazz at Lincoln Center. Honorees like Kristen Wiig, Chelsea Handler, Claire Danes, Hillary Clinton, Tilda Swinton, and Rihanna all turned out for the mingling and partying. Stephen Colbert, who also made the list, gave opening remarks. He gave shout-outs to Kristen and Spanx creator Sara Blakely. Stephen joked, "Kristen, congratulations on the Time 100. Lovely to see you. Her movie, Bridesmaids, huge success, and proved once and for all to the Hollywood boys club that women can have explosive diarrhea, too — you are a feminist icon. Brava, madam. But perhaps the most influential person on the list is here, Sara Blakely, the inventor of the Spanx . . . No one, no one has done more to control women's bodies, except maybe [Catholic] Cardinal Dolan."

It seems the jokes and good times continued for the honorees, who happily posed for photos together. A Stella McCartney-clad Kristen Wiig made the rounds talking to her funny friends like Seth Meyers, Amy Poehler, Louis CK, and Aubrey Plaza. Rihanna hit the red carpet in a pink Marchesa gown before changing to perform on stage, while Claire Danes donned Lanvin to hang out backstage. Secretary of State Clinton may have been the most popular, though, as she shook hands and said hello to NY Knicks player Jeremy Lin, Amy, Chelsea, Harvey Weinstein, Barbara Walters, Matt Lauer, Tyra Banks, and more!

Rihanna is topless in one of the new pictures she's just shared from her January vacation in Hawaii. The singer recovered from a big weekend at Coachella by posting a handful of new images on her Facebook page from the late Winter getaway. Rihanna was among the many stars at Coachella in Indio, CA, on Saturday and Sunday. The music festival gave Rihanna a chance to meet up with her pal Katy Perry. After Rihanna's Sunday show, the two girls had a chance to party together. Now Rihanna's back to focusing on her music and film career. She's in the middle of a global press tour for the blockbuster Battleship and is also counting down until the debut of her new single, "Where Have You Been."

Rihanna wore a Stella McCartney jumpsuit for today's premiere of Battleship in Sydney. She was joined on the red carpet by leading man Taylor Kitsch, as well as costar Brooklyn Decker. Brooklyn Decker's style has been on great display so far during her action movie press tour, and today's gold lamé-sleeved J. Mendel gown didn't disappoint. Brooklyn looked refreshed after a fun weekend with two girlfriends. She had a visit from pals Chrissy Teigen and Erin Andrews, and the trio spent the Easter holiday together sightseeing, lounging in bikinis, and fitting in workouts. The girls even shared a scenic boat tour with Rihanna yesterday. Today, though, was all about business for Rihanna and Brooklyn, who spent the afternoon doing phone interviews.

Rihanna, dressed in blue and gold Pucci, joined her Battleship costars Brooklyn Decker, Alexander Skarsgard, and Taylor Kitsch today at the film's world premiere in Tokyo. Rihanna debuted her darker hair color yesterday at a press conference aboard the USS George Washington in Yokosuka. The stars were whisked back to Japan's capital via helicopter following the press event. Rihanna and Brooklyn tweeted photos and shared their bird's eye view over the city before turning in for the night. The press tour continues for the cast before heading back to the States prior to the film's May 18 opening.

This is Rihanna's first major film role, and it seems she's already eyeing another part. Rihanna's interested in playing Whitney Houston if the right opportunity should come her way. She said, "That's a huge, huge role and whoever does it has to do a good job."

Rihanna's new black hair was on display this morning at a Battleship photocall in Japan. She joined director Peter Berg on the USS George Washington in Yokosuka. Rihanna's costars Brooklyn Decker, Alexander Skarsgard, and Taylor Kitsch were also on hand. It's the latest press stop for the cast. Brooklyn and Alexander took the action picture, which hits theaters on May 18, to Europe last month and attended press events in Madrid, Barcelona, and Hamburg. Promotion for the movie will bring the gang home to the US ahead of its big debut.
