Hilary's Slimming Genes

Hilary Swank’s revealed her secret for staying slim – it’s in her genes.

She’s told People magazine in the US: "I think I've been blessed with my father's metabolism."

"I really appreciate exercise because I think it's a great stress relief. I do this thing called power Pilates, which I love. love, love."

She added: "I try and get out as much as I can but I think in the end I really have to give it up to my genes."

Hilary – who was out for dinner in London at the time – spent the night arm in arm with partner John Campisi.

They’ve been dating since last year.
