Rihanna is rarely non-controversial and is always in the news, whether it is for her songs, her partying or her sense of fashion and dressing. However, this time she may have gone a bit too far. The singer was seen in a very revealing outfit while taking a walk in New York City.

"The 24-year-old wore an eye-popping outfit of a pink, lace bra-top, matching pink mullet skirt and a grey hoodie as she wandered round Soho in New York. She accessorised her interesting outfit with a small, black bag and sunglasses, Converse pumps and super-long yellow nails - but seemed to have left any decent underwear at home," The Sun reported.

The singer was also in the news for an ad campaign for a new fragrance - Rebelle. The campaigns show her almost nude. Rihanna's outrageous dressing sense has sparked concern for her from both family and friends. Apparently , Rihanna's manager and close friend, Jay-Z, has ordered the 24 year old singer to seek help before it is too late.

"Rihanna has been out of control for months. She was supposed to catch a flight back to the UK last week, but she ended up missing it, which was the final straw for management. Jay-Z hit the roof when he found out, and told Rihanna, 'Go to rehab now or I'll drop you from the label'. She's not happy, but she now feels she has no choice," a source told Closer magazine.

Some even speculate the reason behind Rihanna's excessive partying and erratic behaviour is a personality disorder.

"She's reached breaking point. Ri says she's physically and mentally exhausted and feeling lost. I think she desperately needs help and some time off - not just from work but from all the other stresses in her life too," a friend told the Daily Star. The tabloid quotes a relationship psychologist as saying the singer is suffering from "narcisstic personality disorder - a constant need for attention and admiration".

Rihanna was recently admitted to hospital because of exhaustion and dehydration.
