'Teen Mom' Amber Portwood, Gary Shirley Drama- Portwood Reveals Shirley Cheated While She Was In Prison

24-year-old Teen Mom star Amber Portwood has been through enough drama for any one person's lifetime. Having battled a drug addiction and time in prison, the reality TV mom is finally clean and sober. However, while she had kicked the drug habit, she revealed last night on MTV's "Ask The Mom" special that drugs aren't the only drama in her life.

The star of course is referring to the drama that has plagued her with her on-again, off-again boyfriend Gary Shirley. The two share daughter Leah together, but that isn't enough to keep things fine and dandy between the two of them, according to RadarOnline.

Portwood revealed on the special that Gary had cheated on her while she was serving her 17-month sentence in prison.

"When I was in prison, Gary was telling me that we were going to be back together, and he was looking for a house for us, and selling me this big dream," the star explained. "It was a couple of months before I got out that I found out that he was actually with somebody pretty much the whole time! So it was a huge shock."

Well it looks like what goes around come around, as Gary ended up calling it quits with Kristina Anderson, the person her was cheating on Amber with, after he learned she had been unfaithful to him.

Amber is currently single, while Gary has gotten back with Kristina, but it seems that the betrayal has still affected Amber as she revealed, "Honestly, they deserve each other."

It wasn't just Gary who was causing drama in Amber's life, as she explained on the special that her and Teen Mom 2 star Jenelle Evans weren't exactly friendly with each other in the past. However, as we previously reported that two have since worked out their issues and are now even following each other on Twitter.

Fans will get to see all the drama when the original Teen Mom's return for an all-new season early next year.
