Amber Portwood walked off set during the filming of the Teen Mom reunion that aired Tuesday night, but not for the reasons many expected.
Surprisingly, the troubled star's meltdown had nothing to do with her legal drama, her controversial relationship with Gary Shirley or her suicide attempt.
It was the memory of her sister.
Still dealing with the hurt of losing her baby sister to SIDS (Sudden Infant Death Syndrome), Amber got emotional when Dr. Drew brought up the topic.
It's a sad subject, but do you think everything else going on in her life contributed to that reaction? Or was she just caught off guard by the question?
It'll be interesting to see if she can get her life together or if this is yet another sign of bad things to come for Amber Portwood. In the meantime, tell us:
Which Teen Mom star is the best parent?
