Ana Matronic has relished her role as mentor on The Voice - but says she wouldn't want to step into Jessie J's shoes.

The Scissor Sisters star is giving Price Tag singer Jessie's team tips on how to perform during the "battle round" stage of the hit BBC One show.

But she told The Sun that she couldn't be a contestant or coach on the Saturday night show.

"I could never do what the contestants are doing as a singer - I would just throw in the towel. It was a really high-pressure situation," she said.

Ana said of the coaches, who also include Will.i.am, Tom Jones, and Danny O'Donoghue: "I'm not sure I could do it. Jessie has a really tough job."

Ana, whose Scissor Sisters band will be performing on the show in May, also had a dig at Simon Cowell.

"He is someone who has always been in a position of power and you can see that. You can smell the power coming off that guy," she said.

"There is a sensitivity chip missing. I am not one of those women who find success an aphrodisiac."
