Rihanna has posted a series of raunchy photos from her Hawaii holiday online.

The Rude Boy singer shows off her assets in the naughty pictures taken in January. In one photograph, the 24-year-old is seen flinging off her bikini top while covering her chest.

In another image she shows off her svelte figure by rubbing sunscreen over herself.

Other pictures see the star prancing around in a number of different bikinis, striking seductive poses.

It's not the only time the Battleship actress has posted saucy photographs of herself to her social networking pages. She posted a number of risqu snaps of herself at Californian music festival Coachella on her Twitter page over the weekend, including one of herself in a skimpy bikini and another of herself on a man's shoulders while watching a band. She performed at the festival with Calvin Harris and called her best friend Katy Perry up on stage for a hug.

The singer tweeted after the show. "@CalvinHarris I had so much fun with your f**king fanz tonight (sic)," she wrote. "Diz hoodrat $kabii @katyperry also crowd surft n ATE my A$$ during my show (sic)."

Rihanna was also seen getting cosy with New York rapper A$AP at Coachella. She was said to be impressed by A$AP's performance and decided to spend time with him after he left the stage.

"Rihanna took a real shine to A$AP. She couldn't take her eyes off him," a source told British newspaper The Sun.

"She hung around after his set to chat to him and seemed to be a big fan."

Rihanna and A$AP were in high spirits as they toasted one another throughout the night.
