The stunning actress - who is dating Jim Carrey - struggles to maintain any sort of exercise regime and finds it difficult to control her cravings for the corn chip snack.

She said: "I love nachos! I have my once-a-month nachos but with soy cheese and turkey chilli on it, so it's somewhat safe. But it's still a big vice for me, because I have a big bowl of it." Jenny has a home gym but admits she hardly ever uses it for anything other than drying her clothes.
She explained to People magazine: "It mostly dries my clothes but that's where I work out, when I do."

To keep her sexy physique, the former Playboy Playmate sticks to a Weight Watchers eating plan, the famous worldwide diet club of which Sarah Ferguson, the Duchess of York, is the spokesperson.
She said: "I'm still on the Weight Watchers kind of thing, so I just remember to count my points throughout the day. Fruits are zero points, vegetables are zero points, so I make sure I use that to bulk up, and then make sure I have my protein. I usually have my protein at lunch and my carbs
at night - I don't mix protein and carbs."

Jenny, 34, insists she has no intention of succumbing to the pressure to become a size zero and is proud of her famous curves. She said: "You're always going to have your anorexics and you're always going to have your bulimics. But I'm hoping that young girls will look up to the girls that are normal sizes, and know that super, super skinny is not pretty - just ask any guy!

"Ask the guy, 'Do you think that skin and bones running on the beach is attractive?' They'll say, 'Hell no!' "
