Leah Messer admits to using painkillers, cheating with Corey Simms

In her new interview, Leah Messer is owning up to more than losing primary custody of her twin daughters. In new excerpts, the Teen Mom 2 star also confirmed she slept with ex-husband Corey Simms when they were both remarried, and took painkillers. This is the first time Leah’s owned up to those stories despite months of rumors.

In the interview with Us Weekly, Leah confirmed she lost primary custody of Ali and Aleeah to Corey after he claimed the girls were regularly tardy for school. Leah disputed Corey’s story and said she plans to prove it to the court — but she didn’t help her personal case with him by going on to air the dirty laundry about their affair.

“Corey and I did hook up two months after they got married,” Leah said, referencing Corey’s June 2013 wedding to Miranda Simms. At that time, Leah was married to Jeremy Calvert. Although Leah and Jeremy have since divorced, Corey and Miranda are still together, and are expecting their first child. (In September, insiders said Miranda was aware of Corey’s affair with Leah and that they had moved past it.)

Leah also acknowledged that she used the strong painkillers hydrocodone and Percocet after experiencing complications during daughter Addie’s birth. Previously, she denied using anything more than anti-anxiety pills “for about one week.” However, her self-described dealer claimed last year that Leah spent $1,000 per week on Vicodin, Lortab, Percocet and oxycodone. In the excerpts from her new interview, Leah didn’t elaborate on the extent of her painkiller use.

As we reported earlier, Leah said she plans to fight Corey to regain custody of their daughters. She said, “I feel like they should have both of us in their lives. At the end of the day, my kids are going to be happy, and I don’t care what I have to do to make them happy.”

Corey recently deleted his Twitter account and has not spoken out about Leah’s interview.
