Leona Lewis has reportedly befriended a Los Angeles biker group.

The 'Bleeding Love' hitmaker is said to have become a bit of a sensation at one of the city's biker bars thanks to her angelic looks and voice.

A source told the Daily Star newspaper: ''Leona has made friends with a notorious biker group in Los Angeles. Her stunning looks have made her the centre of attraction at the biker bar.

''She hangs out and even drinks beer with them.''

The 26-year-old former UK 'x factor' winner admits she would like to throw off her whiter than white image by following in the footsteps of Gwyneth Paltrow and landing a ''badass'' role in American musical series Glee.

She told E! News: ''I'd love to be on Glee. I'd love to play a rebel. Be a real biker chick in leather and covered in tattoos. A real badass.''

And she has another proposal up her sleeve just in case. She added: ''I could also play like a geek who becomes a swan.''

But when she isn't being bad, Leona embraces her sweet side and channels her energy into protesting against animal testing.

She recently sent a Valentine's card and letter to John Dalli, the European Commissioner for Health and Consumer Policy, asking him to support Humane Society International's CrueltyFree2013 campaign against animal testing.

She wrote: ''Like most girls, I love make-up, but my ethical principles are also very important to me. No new lipstick, eye-liner or other cosmetics ingredient can ever be worth the suffering and death of defenceless animals forced to endure painful toxicity tests.''
