The star, 24, was seen splashing about with mates during a day at the beach on Oahu, Hawaii. She wore an eye-catching blue camouflage bikini — with tassels hanging from each cup of the sexy string top. And she topped off her look with a cheeky straw cowboy hat and gold bangles. Ri-Ri was in town to promote her new film,
Battleship, which was shot on the island. The film comes out in America on May 18 so the would-be actress put in a sultry appearance at Pearl Harbour in a bid to get bums on seats. Of course, the jaunt also gave her a chance to relax with mates in the surf. Rihanna first tried paddle-boarding during her hols on the island back in January. And she clearly took to the sport like a duck to water — as she paddled about with ease this time out.Of course, all that activity will leave a girl gasping for a drink — and Rihanna took regular breaks to sip from a cold beer while laughing with friends. Giggling with girl mates, she also took photos on her phone — no doubt to add to the host of intimate snaps on her Twitter feed.
