World Cup singer 'doesn't like sport'

Anastacia says she is not interested in sport.

The American singer's song Boom has been chosen as the anthem for the football World Cup.

And she says her perfect figure is inherited from her mother and stays the same whatever she eats.

"I thank God for my mother - obviously my figure is down to good genes. I never do sport and I love fast food," she said.

"Perhaps I'll be really fat by the time I release my next album.

"I was really shocked when Fifa's president rang me and asked if he could use my song.

"I think it's great as long as I don't have join the matches - I'd just end up breaking a toenail probably."
