You've seen her on Teen Mom OG numerous times, but who exactly is Kristina Anderson? Gary Shirley's now-wife and second baby mama may seem drama-free these days — especially when it comes to their relationship with Gary's ex and first baby mama, Amber Portwood — but it wasn't always like that.

The 36-year-old — uhh yeah, did anyone else think she was, like, 27?! — allegedly started dating Gary while she was still "happily married," an insider told Starcasm at the time. "Kristina and her husband were very much together then." Yikes. Get to learn more about Kristina below!

She got divorced in 2014

Before meeting Gary, Kristina was married to Gregory Anderson. Court documents reveal that Gregory filed for divorce from Kristina on Valentine’s Day 2014 — savage move, TBH — about a year after she and Gary got involved. The proof? Gary wrote in a Facebook status on January 31, 2014, "Amber and I are done! I have been in love with a new female about a year!" Hmm. Kristina's divorce from Greg was finalized on April 16, 2014.

Later on in July, Gregory filed a restraining order against Kristina but the two were able to eventually work that out as the request was canceled.

She has two daughters

Gregory and Kristina had one daughter together, Karly, who's close to Leah's age, while she and Gary share Emilee, 2.

Leah loves spending time with her

On a recent episode of TMOG, Leah, 9 — Gary's daughter with Amber — wrote down how much she loved her mama and Kristina. We can't think of a better stepmom for her, and we're so happy they all get along!

Teen Mom OG airs Mondays at 9 p.m. EST on MTV.
