Casper Smart could be in trouble with his girlfriend Jennifer Lopez, if allegations that the popstar's toyboy exchanged sexy text messages with a transgendered escort named Sofie Vissa prove to be true.
The Dirty.com's Nik Richie told FOX411 that a member of his 'Dirty Army' - his site's fans-alerted him that Vissa was bragging about a sexual encounter with Smart that began on Instagram.
He said that she has naked pictures of Smart, and is trying to sell them.
Richie's manager is Gina Rodriguez, had no comment. However, her management firm, GR Media, is now tweeting about the attention starting to swirl around Vissa.
