Is this the end of Kailyn & Javi? In Touch has exclusively learned that Teen Mom 2 stars Kailyn Lowry and Javi Marroquin are about to call it quits over allegations of infidelity.

While Kailyn said that all was “good" with Javi at the awards show, an insider says Jo had been spending time in her room.

“Jo even stayed in her hotel room until 3 a.m., talking. She’s jealous of his fiancée, Vee [Torres], and will always have a special place in her heart for him,” an insider explains.

“Kailyn has been telling friends that she and Jo could still get back together."

The source then notes the accusations go both ways.

“They were already having trouble, now Kailyn believes Javi cheated with a woman he’s been hanging out with,” they explain.

“It’s definitely over. It’s sad, but it looks like they could wind up in a nasty custody battle [over son Lincoln, 2].”
