Jessica Simpon's fiance Eric Johnson is alleged to be cheating on the singer according to glossy magazine Star.
The publication has run a story on its frontcover claiming the American football player has been sleeping with his ex-wife, Keri, behind Jessica's back.
"He was sleeping with both of them at the same time," a friend of Keri's is quoted as telling the magazine.
Adding: "One of them made a joke about Eric and his ex-wife still hooking up when he began dating Jessica," recalled the source.
"After the friends left, Jessica asked Eric if it was true, and she blew up after he admitted to it."
Jessica gave birth to her first child - daughter Maxwell - in May with Eric. Let's hope the rumours aren't true for little Maxwell's sake.
