Amber Portwood's legal troubles have the 'Teen Mom' star worried -- and wishing she'd never done the show in the first place.

"I just can't even imagine not seeing my little baby if I go back to jail," she told Life & Style in her first post-incarceration interview.

"It scares me so bad," she added of the possibility of two-year-old Leah being taken away from her.

Portwood was arrested for allegedly assaulting ex-fiance -- and father of her child -- Gary Shirley, in an incident that was caught by MTV's cameras.

Amber regrets signing on to the series in the first place, since she believes the incident would have gone unnoticed had it not been for 'Teen Mom.' "I wouldn't have been in jail because nobody would have known about it," she explained.
