Experts: Being on 'Teen Mom' Makes Its Stars Unstable
'Teen Mom 2' star Jenelle Evans was arrested for assault over the weekend after a video surfaced of her brutally beating another teen. Evans has also incurred charges of drug possession and breaking and entering.

Her fellow teen mom, Amber Portwood, was arrested in December and spent 24 hours in jail on charges of attacking her baby daddy in front of their two-year-old daughter.

Now experts are raising the question of whether 'Teen Mom' is to blame for taking obviously unstable teenagers and thrusting them into a spotlight they are not ready to handle.

"These are not the most stable girls to begin [with]," says clinical psychologist and contributor Jeffrey Gardere. "They have a lot of issues and stresses from being teenagers who are pregnant, and now they are in the public eye. Some of them are making a lot of money, and that is a stress in itself, which can cause some real behavioral issues."
