Rihanna can't help but get down and dirty in some of the pictures — guzzling beer, grinding with a girlfriend, and slathering suntan lotion all over her exposed body.

The 24-year-old S&M singer's love life has been the subject of endless speculation, as she's been linked to ex Chris Brown and Two and a Half Men star Ashton Kutcher.

When recently asked about her love life during a press conference the Barbados beauty responded, "I'm happy and I'm single, if that's what you're really asking."
