Jenelle Evans is speaking out amid reports that ex-fiancé Nathan Griffith had an account on Ashley Madison. The popular cheating site was hacked nearly two weeks ago and has exposed several prominent figures in politics, business and entertainment. Among them were Josh Duggar of "19 Kids and Counting," and "The Real Housewives of New York City" star Kristen Taekman's husband, Josh Taekman. New reports claim to have confirmed the email address on the site did belong to Griffith, 26, and Evans, 23, is not happy.

Radar Online attempted to reach out to Griffith about the email address, which he initially said did not belong to him. The site reports, however, that it is linked to his personal Facebook page. He has since simply denied to comment. His former fianceé, on the other hand, was more than willing to discuss the matter. Evans, who shares a child with Griffith, said she wasn't surprised to learn he had been registered on Ashley Madison. The "Teen Mom 2" star added that he was an embarrassment to himself and those associated with him.

"Once a cheater, always a cheater," she said. "I think he embarrasses himself and whoever [is] associated with him -- especially the girl he's with now, because supposedly she doesn't believe in sex before marriage. But Nathan does." 

Sources close to both Evans and Griffith told Radar the email address was legitimate. They also confirmed that he had signed up for Ashley Madison in May or June of this year. At the time, he and Evans were "separated." He was, however, seeing his current girlfriend, according to the source. 

Evans and Griffith got back together shortly after having a domestic dispute in March in which he reportedly pinned her against a toilet in an attempt to rip her engagement ring off her finger. Griffith was arrested in the incident and charges were filed against him. They split once more in May after Evans vandalized Griffith's car and choked him. She turned herself in shortly after. The pair reunited after the dust settled and things seemed to be looking up for them. Unfortunately they split yet again in early August. 

Griffith isn't the only one Evans has an issue with. As we previously reported, the mother of two was arrested on Aug. 20 after a heated altercation with her former fiancé's new love interest. According to reports, Griffith arrived at Evans' home to pack his belongings and brought his new girlfriend along with him. Furious, Evans is said to have gotten into a scuffle with Henry, which ended in her throwing a glass and ultimately being arrested. She was taken to Surfside Jail in Myrtle Beach, South Carolina, where she stayed for about six hours before being released.
