That's strange considering it was "Papa Joe" who got them together in the first place... perhaps he got jealous *retches*
According to FOX: "Joe's meddling ways most likely took its toll on the relationship, which is the reason why they split the first time 14 months ago. Joe promised he'd take a step back when the couple reunited but he was still too involved. At one point Joe was even giving Tony football advice which doesn't go down well."
Back in March, another source in the form of a helpful "friend" had said: "Joe now feels that Tony has become too much of a distraction for Jessica. Any free time she has, Jessica wants to spend with Tony. But rather than blaming his daughter's work ethic, Joe points the finger at Tony."
Other ever-helpful and perennially nameless "sources" are claiming that it wasn't Joe who got an attack of the green-eyed beast, it was Tony - because Jessica was still getting texts off John Mayer:
"They were hanging out and he picked up her phone and she got defensive about it. Tony found messages from John and went ballistic. He dumped her right then. He walked out and that was it."
Worse, she's probably just signed up to receive Mayer's countless Twitter updates to her mobile.
