Rihanna recently suprised fans at Kanye West and Jay-Z's London show

Getting drunk, visiting strip clubs, posing provocatively on Twitter... so far, so Rihanna.

But the singer's hardcore partying took a troubling turn recently when she ended up on an drip after a night out.

Now those close to her are urging her to seek help.

Bishop Vibert Lowe, who's known Ri-Ri, 24, since she was a child in Barbados, tells Now he fears she'll end up like Whitney Houston, who died in February after years of battling drink and drug addiction.

Vibert, 64, says: 'I'm very concerned. We all are.'

It comes after Rihanna Tweeted a pic of herself on an IV drip after an all-night bender at New York's Met Ball - although she insists she sought medical help because she had flu.

'She's going the wrong way,' says Vibert. When I saw the hospital picture I was so disturbed.

'She's drunk a lot, she's smoking a lot... It's really bad behaviour and she's getting worse.

'She could head down the same route as Whitney Houston. She promotes a bad girl image and that's not responsible to her fans.'
