Hollywood sweetheart Meg Ryan has taken drastic measures to shed her saccharine image.The actress, 46,  has gained TEN STONE in a new movie comedy called 'My Mom's Hot Boyfriend.'  But unlike some of Hollywood's yo-yo dieting actresses, the weight gain is only temporary as the actress' 18 stone transformation came courtesy of a very convincing fat suit. Meg's metamorphosis from girl next door to the porky neighbour took three hours in the make-up trailer each day to create.

She said: 'I didn't mind the make-up. I like a character who is all about transformation."  In the film, Meg eventually sheds the excess pounds and dates Hollywood heart-throb Antonio Banderas.She added: 'She was enormous, and now she's foxy.'  Ironically, Colin Hanks - son of her 'Sleepless in Seattle' and 'You've Got Mail' co-star Tom Hanks - plays her on-screen son. 

He's an FBI agent who returns home after a three-year assignment to discover his chunky mother is now super-hot.But his life turns into a nightmare when he's forced to spy on her every move because her dashing new boyfriend - alias Banderas - may be an international art thief.
