Rihanna has been "going a bit wild" during her extended holiday.

The singer has enjoyed a lengthy break in her native Barbados recently, following the end of her Loud tour and the release of her new album.

There have been suggestions she has been partying too hard while there, with some claiming she has been smoking marijuana. However, those close to her insist she is just having fun while on holiday.

"Right now she's just letting off steam," a source told Look magazine. "Ri's been working hard and has just had her heart broken by Chris [Brown] again, so it's natural she wants to get drunk and go a bit wild. But we're all sure she'll get back to her usual happy self once she gets home and back into her routine."

There has been speculation Rihanna and her ex-boyfriend Chris have been spending time together lately, but it's not thought they are back together.

They have been spotted in the same nightclub but Chris has a new girlfriend. It's thought he has been texting Rihanna, but it's more about the pair of them moving on from their fraught relationship.

"They were each other's first loves and that's something that'll never go away, which is why they were tweeting one another at the end of last year," the insider added. "But they were also really bad for each other. They argued all the time, and everyone knows the violent way the relationship ended."

The former couple split three years ago after an argument turned violent. Chris was charged with assaulting the pop beauty and served with a restraining order.

The protective order slammed on the rapper was lifted a year ago. It required that they have no contact with each other.
