Leah Messer took to Twitter on Wednesday to deny a recent dating rumor.

Following speculation about a potential relationship with a man seen on her Instagram page, the Teen Mom 2 star revealed to her fans and followers that her alleged "mystery man" was gay and married.

"I don't think Brians HUSBAND would be pleased if Brian was my mystery man!" Messer tweeted on Wednesday.

This isn't the first time Messer has been faced with romance rumors in recent months. As fans may recall, she sparked rumors of a reunion with her ex-husband, Jeremy Calvert, in April, but he quickly shot down the rumors.

“This past weekend, I went to the bar by myself because basically everyone in town was at a concert that was going on in Charleston,” Calvert told The Ashley's Reality Roundup of their outing. “After the concert, everyone started coming into the bar including my friends and Leah and her friends. It wasn’t planned or anything, it just happened we went to the same place."

“I was single, so I didn’t see anything wrong with taking an innocent photo with my ex-wife,” he continued. “We have a child together, and we’re not going to start screaming at each other or anything. We get along and we act like mature adults for our kid.”

As for a reunion, Calvert confirmed that his friendly antics with his ex-wife were just that and nothing more.

“Me and Leah are not back together, we’re strictly friends,” he said. “If I run into my ex-wife, we’re going to act like mature adults for the sake of our child. If people don’t understand that they can kiss my ass.”

To see more of Leah Messer and her co-stars, including Jenelle Evans, Chelsea Houska, Kailyn Lowry and Briana DeJesus, tune into the upcoming premiere of Teen Mom 2 season eight, which airs on Monday night, July 17, at 9 p.m. on MTV.
