Rihanna Bikini Pictures

Rihanna was in a string bikini yesterday for an afternoon of surfing in Hawaii. She wasn't photographed actually paddling, but seemed content to soak up the sun while laying out on the board. We've seen lots of Rihanna bikini pictures during her latest tropical getaway. She's been all about wearing bathing suits, whether horsing around with her friends or even working out on an elliptical. Rihanna certainly earned the downtime after touring the world in the last year and releasing a new album. She'll be back to work soon, though, when she does a duet with Coldplay at the Grammys on Feb. 12.

Rihanna got away to the Hawaiian Islands for a little relaxation earlier this week. She's been spending her days by the beach, in the water, and hanging with friends — and she captured it all on Twitter. Rihanna shared personal pictures of her vacation including hot snaps of her skimpy bikinis and fun moments with pals. Click through to see more from Rihanna's hot Hawaiian getaway!

Rihanna slipped on a silver cutout suit for another afternoon in the Hawaiian sun today. She joined a group of friends for a boat ride after being spotted at the beach solo just yesterday. The singer has been lounging in sexy swimwear during her downtime on the tropical island, but she's showing even more skin in her latest ads. Rihanna posed in lingerie for her new Emporio Armani Underwear promos, which were just released. She's taking a break from making music while on vacation, though her "We Found Love" is still holding on to its number one status.

Rihanna continued her Hawaiian vacation yesterday with a solo beach stroll. She left her hotel and set out on foot for the beach. Rihanna's bikini body was covered up, but her two-piece was still noticeable under a pink cutout dress. She's on her latest vacation following the November release of her new album, Talk That Talk. The first single off the record, "We Found Love," is sitting at the top of the charts, giving Rihanna her 11th number one hit.

Rihanna's return to Hawaii comes more than a year after she filmed Battleship with Alexander Skarsgard, Brooklyn Decker, and Taylor Kitsch there. Their action adventure, based on the board game, hits theaters this Summer — check out Rihanna's cameo in the first Battleship trailer.

Rihanna hit the beach in her home country of Barbados this afternoon. She splashed around in the water and soaked up the rays, but Rihanna's bright day didn't last since she tweeted "the sun just went hiding somewhere, and I'm still not dark yet!!!" The weather didn't stop Rihanna from flaunting her fit physique, which landed among the hottest bikini bodies of the year.

She's been relaxing in a two-piece since arriving in the Caribbean on Christmas Eve, though she took a break from the sand to celebrate the holidays with her family. The getaway is a relaxing end to a busy 2011 for the singer, who toured the world, teamed up with Emporio Armani to design a capsule collection, and released her sixth album. Talk That Talk was one of your favorite pop albums and fans are still waiting to see which single she chooses next.

Rihanna popped up in Ireland today to shoot a new video for her single "We Found Love." She's fresh off a stint in Brazil performing at the Rock in Rio event. Katy Perry, one of Rih's best buds, was also in the city to perform at the weekend-long festival. There was enough downtime that Rihanna could throw on a bikini to chill at the beach with friends between rehearsals and her gig. Amid her hectic schedule of jet-setting, Rihanna also managed to film a cameo for Extreme Makeover: Home Edition. Her episode, the two-hour season premiere, aired last night and also featured special guest First Lady Michelle Obama.

Rihanna took a break from touring to hit the beach in Rio de Janeiro on Sunday. Rihanna slipped on a printed bikini for the outing and showed off a new henna tattoo on her left arm. She was joined by friends, though once other beachgoers spotted the singer on the sand, she had to quickly escape the swarms of people and return to her hotel. She was safely back in the spotlight on Monday, though, when she waved to fans from the balcony of her room. Rihanna has a few more days to soak up the sun in Brazil before she heads to the UK to continue performing, but first she'll release her latest single, "We Found Love," tomorrow.

Rihanna made the most of her final hours in Sardinia, Italy, yesterday, first stopping at Prada then partying late into the night with girlfriends. During her latest shopping spree, Rihanna stepped out wearing a sequin bikini top, but earlier in the week she showed off her sexy body in a bright blue bikini and toasted champagne with friends wearing a colorful cutout one-piece. Rihanna's been sailing around the Mediterranean for the past week, but even on vacation she managed to release her latest video, "Cheers (Drink to That)."

Rihanna soaked in the sun on a yacht off the coast of France while wearing a hot blue bikini today. Rihanna is enjoying a couple days off after getting paid a cool $2 million to perform at the V Festival in the UK on Saturday and Sunday. From there, she jetted right off to the South of France, where Rihanna quickly slipped into her bikini to party with friends. She is rumored to be skipping this weekend's VMAs, since she didn't score any solo nominations. Fans, though, will get a sneak peek at her new music video with Nicki Minaj for the song "Fly" during the award's preshow.

Rihanna pulled out all the stops modeling the shortest of shorts for her two sold-out shows over the weekend. She coheadlined England's V Festival Saturday and Sunday, joining Eminem on stage both nights for a duet of their chart-topping hit "Love the Way You Lie." Rihanna relocated to the South of France today for her latest bikini-filled break from touring. She boarded a yacht docked off the France's southern coast wearing a black bandeau then slipped into a wild cutout one-piece and sipped champagne with friends. Rihanna has lots of reasons to celebrate, collecting nearly $2 million for her performances at the festival while Eminem reportedly took home $3.3 million. Rihanna and Eminem could reunite this weekend at the MTV Video Music Awards, where their song is nominated for best male video, best cinematography, and best direction.
