Kristen Stewart has praised her Twilight co-star Taylor Lautner and called him “buff”.

The young star nearly quit the films before New Moon but instead decided to hit the gym to keep the role of Jacob.

Stewart told Sugar magazine: “Taylor still playing Jacob was the coolest thing. It was under deliberation so I'm glad he did it. And he looked so buff!

“I saw the steady progression from Twilight Taylor to New Moon Taylor - but if I hadn't, I don't think I'd have recognised him.”

Fellow Twilight lady Ashley Greene also spoke to the magazine about her male co-stars.

She said Lautner is too young for her to fancy but admitted its different with Robert Pattinson.

Greene explained: “I see him (Taylor) more as my little brother than a love interest. With Rob I can definitely see the appeal. He's very talented and I think talent makes a guy sexy.”

“We all kind of flirt with each other. We share this intense bond.”
