Is Leah Messer living with her rumored boyfriend, T.R. Dues?

Why Is Leah Messer Flooding Your Facebook Feed With Pregnancy Posts?

Although the Teen Mom 2 star has denied dating her personal trainer, Corey Simms revealed during last night's episode that his twins have told him otherwise.

“Are you dating a new guy that has been around my children?” Simms asked Messer, according to an OK! Magazine report on Thursday. “Does he live with you?”

When Messer claimed in response that she didn't have a boyfriend, Simms then asked, “Why do the girls tell me he lives with you and ya’ll sleep together?”

News of Messer's rumored romance with Dues first hit the web in June, around the time her divorce from second husband, Jeremy Calvert, was finalized. At that time, Radar Online claimed the two had moved in together after just weeks of dating -- and that her children's fathers weren't thrilled.

“T.R. moved in with Leah and her parents after just a week of dating!” a source told the site. “When mutual friends told Jeremy about this new guy, he called Leah and flipped out for letting a stranger hang around Addie. Leah initially denied the relationship, saying that they’re not official, but then confessed that something’s going on.”

Two months later, a source told a separate Radar Online report that Messer and Dues had gotten a new home in Charleston, W.V., where they were living with her three daughters and his two sons.
