Jesse James fiancee Kat Von D is losing her hair due to the stress she's suffered over the past year

Aw, poor thang…

Kat Von D is so stressed out that it’s beginning to take a toll on her hair, which RadarOnline.com has exclusively learned is falling out, pushing the LA Ink star to start wearing wigs.

According to a source close to the 29-year-old, breaking-up and then getting back together with fiancé Jesse James, along with her TLC show being canceled, have all attributed to the stress that’s causing her to bald at such a young age.

“Kat totally has bald spots and it’s from stress,” the source told RadarOnline.com. “It’s worse than anyone her age should have.

“The combination of all the treatments she does to her hair and stress have finally caught up with her. She’s started ordering wigs along with the hair pieces and extensions she already uses.”

Kat infamously started dating Jesse after his very public cheating scandal on then-wife Sandra Bullock, and after his divorce to the Miss Congeniality star was final he was engaged to Kat just six months later.

“I feel really bad for her because the bald spots are horrible,” the insider said. “The stress of losing her hair is only stressing her out more and making it worse!”

Somewhere, as we speak, Sandra Bullock is laughing saying “How do you like that bald-headed b!*$# NOW?!?”
