Nathan Griffith, who recently broke up with Teen Mom 2 star Jenelle Evans, had an Ashley Madison account registered to his email address. Griffith has denied the allegations.

Griffith's email address, "Nate_griff42@yahoo.com" showed up as that of a registered Ashley Madison member in leaked data released by hackers earlier, reported Radar Online. Jenelle Evans slammed her ex-fiancee saying, "Once a cheater, always a cheater."

"I think he embarrasses himself and whoever associated with him, especially the girl he's with now because supposedly she doesn't believe in sex before marriage. But Nathan does," she told the publication.

A source close to Evans and Griffith confirmed to the website that it was indeed Nathan's email that showed up on the account. Griffith made the account around May or June, when he was on a break from Evans, the source revealed.

"He was separated from Jenelle," the source said. "But he was seeing [his new girlfriend] Jessica. He claimed he made it because he couldn't remember his gmail password and was locked out of his old email."

"It's definitely not shocking that Nathan has an Ashley Madison account," the source continued. "Jenelle is glad not to be the one having to deal with his antics anymore."

Jenelle called off her engagement with Nathan Griffith in the first week of August. She was arrested recently for assaulting his new girlfriend Jessica Henry. Radar reported that things got heated when Nathan Griffith brought Henry to Evans's place after Jenelle asked him to clear his things out of their house, the insider claimed.

"This really made Jenelle mad. They ended up getting in a fight and she threw a glass at Jessica. So Nathan called the cops."
