Back to Black singer Amy Winehouse is bisexual and has had relationships with women, her friends have claimed.

She is said to have told close friends: “There is something about being with a woman that is very satisfying. I don’t care what people think about me being bi – I do what feels good.”

One friend of the singer, speaking with her permission to the News of the World, said: “There is nothing restrained about Amy’s sexuality.

“She doesn’t hold back and says what she feels. She often talks about other women. Her favourite is Cheryl [Cole], who she really fancies. Most women can appreciate another woman’s beauty but Amy definitely takes that to the next level.”

Winehouse’s ex husband Blake Fielder-Civil denied rumours last week he was dating a trans woman.

The Winehouse lookalike, named Mia McHugh, 17, told the Sun she and Fielder-Civil had had a relationship for months.
