Friends Are Worried About Rihanna's Drinking

That Rihanna is exhausted is a bit hard to deny right now, given her recent performance at the 2011 Jingle Bell Ball in London. However, a new report claims this might be the least of her problems.

Star Magazine claims in its latest print issue (story via here) that good friends Katy Perry and husband Russell Brand are worried that Rihanna may be drinking too much.

The two are so afraid about her health, that Katy has even urged her to seek therapy and take a break to take better care of herself, the tab alleges.

“Following Rihanna’s recent hospital visit, 'Katy told her she has to slow down,' a source says, adding that Katy even suggested her BFF come stay at her home,” the report notes.

Because she won't listen to advice, Katy is “desperate” to get her into treatment, whether she likes it or not.

In the meantime, though, she's working to make her see she's on the wrong path, one that is heading to self-destruction.

“Katy begged Rihanna to take some time off and get therapy. Rihanna’s been running on empty. And rather than resting, she’s drinking and clubbing until the early hours of the morning,” the unnamed insider is quoted as saying.

Moreover, Rihanna's current problems with alcohol seem to be stemming from her failed relationship with Chris Brown, which violently ended when he attacked her in a fit of rage.

She is also unhappy with her current situation with her record label, claims the celebrity publication.

“Rihanna’s been self-medicating with booze ever since their split, and it’s not getting better. She calls Katy in tears, saying how down she is and that her life’s controlled by her label. She just wants a loving boyfriend,” the insider adds.

Even Russell Brand, Katy's husband, who didn't like Rihanna at first, is worried sick and is telling Katy she should “step in” and do something about this until it's not too late, it is being said.
