New Delhi, Mar 2 : Jessica Simpson `can''t resist' junk food - and has reportedly re-hired her former personal trainer in a bid to shed a few pounds.

The singer/actress - who recently hit the headlines after sporting a new, fuller-figure - has embarked on a strict fitness regime with Mike Alexander in an attempt to control her cravings for calorific fried food.

"She just can''t resist junk food. She literally needs to be watched all the time," a source said.

"Jessica has a problem with binge eating, which is usually triggered by stress.

"Jessica''s most recent violation was indulging in the terrible trio of chicken wings, nachos, and alcohol at the Great Dane Pub in Madison, Wisconsin," the source added. (ANI)
