First Chris Brown dismissed rumours that he was dating Rihanna, and now the singer herself has spoken out, denying that she and Chris are an item, saying: "We are best friends, honestly, like brother and sister."

“I won’t say that we’re just friends – me and Chris are really best, best friends,” the 20-year-old star told MTV News at Saturday’s Kids’ Choice Awards in Los Angeles.

The two singers have been the subject of a flurry of rumours about their relationship, after photographs were published of them spending time together.
