The `A-Team` actress sticks to a strict diet and exercise regime when she is shooting her movies, which means she has to go without the calorific dairy delight, much to her annoyance.
She told BANG Showbiz: "I have a pretty good diet, pretty much, when I`m working. "When I`m not working it goes out of the window. I`m very much a savoury person. I love pizza, bread, pasta and cheese.
"Cheese on top of cheese, on top of cheese! It`s the best."
Jessica has been in the UK this week promoting `The A-Team` and admits her favourite thing about coming to Britain is the food.
The 28-year-old beauty has a particular fondness for crumpets - a delicious bread snack traditionally topped with butter and jam.
Jessica - who plays military hardliner Charisa Sosa in the reimagining of the 80s TV show - said: "I love the British food! What are those things... crumpets! Crumpets are amazing. I had poached eggs on them the other morning but I really like butter or jam. I`m a great fan of, oh what`s that stuff again? Cottage cheese!"
Earlier this month, Jessica admitted she has to work hard to maintain toned physique.
She said: "This doesn`t just happen naturally. I eat very well and that means staying away from sugar, coffee, bread, wheat and gluten - all the fun stuff that everyone wants to eat! It`s hard but I`m very disciplined."
