Amy Winehouse snubbed Sia collaboration

Troubled singer Amy Winehouse snubbed a collaboration with Aussie songstress Sia - because she was "intimidated" by her, it has been revealed.

Sia, 33, best known for her work with Grammy nominated downtempo group Zero 7, explains: "Amy said: 'No way. I'm intimidated by you. I've been listening to you since my teens.'

"I was totally shocked – because she’s my favorite contemporary voice."

Meanwhile, the 'Rehab' singer, 24, is reportedly set to launch her own fashion range - including clothes, make-up, hairspray & liquid eyeliner - so that fans can copy her unique style.

A pal said: "Amy’s style has been copied by girls around the country and there’s a lot of money to be made. It’s a very distinctive look.

"She wants to bring out a range of cosmetics and fashion products. There could be hairspray, head scarves, liquid eyeliner, perfume.

"All the things that are distinctive of her look.”

A fashion industry expert - who believes the singer's products could become a huge hit, added: "I think this stuff would sell very well in London.

"She has become a fashion icon despite not always looking too fresh."
