The 'Dukes of Hazzard' actress, who split from US musician John Mayer in the
summer, is said to be feeling lonely and has started gorging on French fries
to cheer herself up.
A source said: "Jessica jokes about wanting a boyfriend, but it isn't funny.
It hurts her to see her exes moving forward.
"She keeps getting crushes on the kind of guys who will let her down. That
triggers her cravings. She usually gives in to them at bedtime. When she is
at a hotel, she will often order a plate of French fries as a late-night
snack. She knows it isn't healthy, but she doesn't have a lot of willpower
right now."
Jessica has reportedly gained 10lbs since September and has turned to close
friend Mike Alexander to help get her back into shape.
The source added to the National Enquirer magazine: "Jessica recently binged
on buffalo wings and cupcakes and gained some weight. She feels horrible.
She is determined to work those pounds off - and she wants Mike to help her
do it. He literally got her butt into shape for 'Dukes of Hazzard'.
"He will give Jessica the disciplined 'boot camp' workout she needs - lots
of cardio, lots of lunges and weights.
"I wouldn't be surprised if she ended up in a romance with Mike. He has
always been there for her. Jessica leaned on him when her marriage to Nicky
Lachey fell apart.
"She feels safe when Mike is around."
