Kim Cattrall packed on 20 pounds for porn star role

Kim Cattrall's weight gain for her Meet Monica Velour role was a bargaining point between the Sex and the City actress and producers. "They asked me to gain 30 but I didn't want to make myself sick," says the 54-year-old.

"We made a deal saying I would gain 15 lbs before the film and 5 lbs during," continues Kim Cattrall. "But I did enjoy grabbing my stomach and feeling what that extra weight felt like."

Though Kim, who is also a spokesperson for I Can't Believe It's Not Butter, may have enjoyed her time on the pleasantly plump side, getting the Meet Monica Velour weight to come off wasn't a cake walk.

"I found it so easy to put it on and so terribly hard to take it off and that's why this product was really useful because I didn't have to sacrifice very much," Kim Cattrall told Access Hollywood. "But it was -- Eat Right For Your Blood Type is a great diet and I've used that before."

"It was painstaking -- exercising a lot and being on the diet and not snacking," Kim added of getting back to her svelte shape. "My appetite did shrink and I did lose the weight."
