Miley Cyrus threw on her two-piece yesterday to join her boyfriend, Liam Hemsworth, at Orchard Lake in Michigan. The couple ventured into the water to share a jet ski when they weren't hanging on a dock with pals. As a complement to Miley Cyrus's bikini, she also debuted some body art. Miley's new tattoo features two lines on one of her fingers. Miley explained on Twitter that it was to support gay marriage, writing, "All love is equal." Miley was able to visit with Liam now that she's wrapped up her Gypsy Heart tour. He's staying in the state to shoot AWOL, and Miley will be back on the road soon if she chooses to attend the Teen Choice Awards this Sunday in LA. She's up for two awards, including best TV actress for Hannah Montana as well as Choice Red Carpet Fashion Icon.

Kate Middleton stocked up on groceries today at a local store in North Wales, which is nearby where her husband, Prince William, is stationed as a search and rescue pilot. The Duchess of Cambridge was casual in her jeans, flats, and scarf, and just this morning she went on a romantic walk with her duke, who was wearing his own purple sweater as well. It's back to regular life for Duchess Catherine and Prince William as they come off a celebratory weekend in Scotland at his cousin Zara Phillip's own royal wedding to Mike Tindall. The Duke and Duchess of Cambridge reportedly let loose at the party after the ceremony, with Prince William even performing karaoke to Bon Jovi's "Livin' on a Prayer."

Rihanna hit the streets in Barbados today, dressed in a sequined bikini and feathers for the annual Kadooment Day parade. The weather didn't cooperate for her hometown celebration; however, she made the best of it. Rihanna's festive outfit drew attention from the crowd and she recently shed light on how she styles herself, saying, "Getting dressed, I want to pick the most bizarre pair of shorts so I can figure out how to make it look right, or work an outfit that will make people go, 'What the hell is she wearing?'" Rihanna's hair has become a big part of her style as well, and it seems she may be following the same trend as her best friend Katy Perry by ditching her signature crimson locks for a lighter shade. Rihanna wrapped up the North American leg of her tour and is enjoying a short break in the Caribbean before embarking on upcoming dates in the UK and Brazil. Right now she's focused on her music and the tour, but next Summer we'll be able to see her on the big screen when Battleship sails into theaters.

Mila Kunis and Justin Timberlake spent their Saturday shopping separately around Paris. The Friends With Benefits stars took a break and visited French boutiques after debuting their romantic comedy in both Moscow and Berlin earlier in the week. Justin was spotted at Hermès, while Mila stopped by several designer outposts, including Isabel Marant, Givenchy, Chanel, and Céline. Mila has been sporting a healthy glow during their overseas trip, which may be partly due to her rumored investment in a pricey new beauty treatment. Mila reportedly spent $7,000 on a Borba facial that uses rubies and diamonds to exfoliate! Meanwhile, Justin recently made a big purchase of his own, teaming with an advertising company to put up $35 million for an ownership stake in MySpace.

A newly blond Nicole Kidman arrived on set with her costar John Cusack in New Orleans today. Production on The Paperboy has begun, and director Lee Daniels put together an all-star cast including Matthew McConaughey, Zac Efron, and Tobey Maguire. Nicole was one of the last actors to sign on. She was a replacement for Sofia Vergara after the latter had to drop out due to scheduling conflicts with Modern Family. The new hue comes as a big change for Nicole, who recently stepped out in NYC with her husband, Keith Urban, modeling her trademark red tresses. It's been a busy year personally and professionally for Nicole, since she wrapped up work on HBO's Hemingway & Gellhorn this Spring and kicked back on a family vacation in Australia with Keith, Sunday, and Faith Urban last month.
