'Teen Mom' Amber Portwood Blasts Gary Shirley's Girlfriend: MTV Star Calls Her "Fakest" Person!

Teen Mom star Amber Portwood has had many ups and downs on the hit reality show, especially when she went to prison for a drug addiction. However, the MTV star is now taking her baby daddy Gary Shirley's girlfriend to task for commenting on her relationship with daughter Leah.

According to Wetpaint, in this week's episode of "Unseen Moments," Amber is shown a clip of Kristina Anderson bringing the reality mom down, while boosting herself up.

"I've been there for Leah, and I kind of felt pushed aside figuring I have been there for Leah her first days of Pre-School... I consider Leah my very own," Kristina said in the scene.

After seeing this, Amber was furious and blasted Gary's baby mama for making it seem as though she wasn't a good mom to little Leah.

"She is one of the fakest people I've ever f**king seen in my life," the newly engaged star said. "That just pissed me off. The way that her and Gary met, she was married [and] cheating on her husband. They got divorced because of her and Gary! I'm happy she was in Leah's life when I was gone, but don't step on my f**king toes."

"That's not your kid," she went on. "Thank you for being there, honey, but that's not your kid, that's my kid."

As MStars News reported, Amber has been in a better place ever since leaving prison and getting engaged to a man named Matt Baier, whom she met on social media.

"My life now with my new fiancé is amazing and our relationship is completely different than what mine and Gary's was," the MTV mom told E! News. "There's not really fighting or anything like that. It's not perfect, but we're so happy together. I never thought I could find another man that could make me feel love again, honestly. I feel more love for him than I ever have for anybody."

Whose side are you on: Amber or Kristina?
