Amber Portwood is fresh off of a Twitter meltdown. The Teen Mom OG star went after her ex-boyfriend and the father of her oldest child, Gary Shirley earlier this week. Portwood was upset because she had previewed the new episode ahead of its airing. Her tweets were about Shirley’s comments regarding her lack of parenting their child, and his wife, Kristina sounded off as well. There is a lot happening in her life, and now, she is having to face it all head on.
