Lily ColeLily Cole last nightSupermodel Lily Cole isn't scared of putting on weight.

The slimline model-turned-actress told Sky Showbiz she has no problems shedding her skinny image if the right part comes along.

"If it was appropriate to the role, I'd have no reason not to," Lily revealed at the London premiere of The Imaginarium Of Dr Parnassus.

In the past, Lily has been criticised for her skinny frame, and in 2006 was lambasted by then-culture secretary Tessa Jowell who said she was so thin she should not be allowed to feature at London Fashion Week.

But it looks like modelling has now taken a backseat.

The Chanel couture-clad clothes horse told us she is "definitely" serious about acting.

The 21-year-old Cambridge University student plays the film's 15-year-old lead actress, alongside the late Heath Ledger, and Hollywood heart-throbs Johnny Depp, Colin Farrell and Jude Law.

Lily said: "I'm sad Heath's not here."
