'Teen Mom': Then & Now
Amber Portwood ("Teen Mom" Season 4)
Amber Portwood: Now
Portwood's problems lasted long after her time on "Teen Mom." In June 2012, the 22-year-old was
sentenced to five years in prison for violating probation after failing a urine test after a felony drug charge. Although she's expected to serve only two years in prison, she had to make another huge sacrifice, signing over full legal custody of 3-year-old Leah to her ex Gary Shirley.
