‘Teen Mom 2’ star Leah Messer has had her fair share of scandal these past couple of years and here is a new one we can add to the list. Apparently she and ex-husband Corey Simms “hooked up” in late 2014, while Leah was still married to Jeremy. Corey was and is still married to Miranda, who is expecting a child with Corey sometime in January of 2016.

According to the very close and reliable sources that spoke with The Ashley’s Reality Roundup, Corey was using a stealthy smart phone app to conceal his conversations with Leah leading up to their hookup, which was rumored to have happened in the back of Corey’s work truck.

“Corey regrets it, especially since Miranda is pregnant now,” one source tells The Ashley. “But he had been talking to Leah for a while, so they both knew what they were doing. It wasn’t just a random mistake. But Miranda forgave him.”

The incident is most likely why Miranda ended up flipping out on Leah at the season 6 reunion taping. Read all about that here.
