As it turns out, Jessica Simpson’s meddling father wasn’t the only factor in her recent relationship woes with Tony Romo. Although the two are now back together for “a trial thing,” a friend of the singer-turned-actress spoke to In Touch about Jessica’s jealousy issues.

“Jessica can be so insecure when she is with Tony, and it only gets worse when he is around women,” said the friend.
While the pal insists that any female competition is bound to upset Jessica, the subject of Tony’s ex-girlfriend Carrie Underwood is what really riles her.

“(Jessica) is really upset that (Tony’s) still communicating with Carrie,” the source said. In fact, the insider revealed that the Dallas Cowboy quarterback frequently contacts the country-music star via e-mail and text messages even though he knows it bothers Jess. “She had specifically asked Tony to stop,” the insider added.

And “things got worse for Jessica” when Carrie broke up with Chace Crawford back in March, according to the friend. That’s when Jessica allegedly began to fear Carrie really could win Tony back.

“Jessica has to tone down how jealous she gets over things like this,” the friend adds. “It took a toll on their relationship.”
