Usually we think of Poppa Simpson as overprotective, but no father wants to hear the kind of things John Mayer said about Jess!
Unbeknownst to Jessica, Poppa Simpson reportedly called Mayer and told the prick off!
"The conversation was pretty one-sided," says an insider. "Joe told John that he best not even think of uttering Jessica’s name again."
Mayer argued that he was "praising" Jess by calling her "sexual napalm", but Joe wasn't having it.
"Joe told John to stay away from his family and man-up and apologize for his comments," said the source.
The source goes on to say Mayer shot Jessica an e-mail stating that he was "sorry if the interview offended her," which is such a typical half-assed non-apology for a self-righteous douche to give!
What about saying sorry and honestly meaning it?!
Update: A source close to Poppa Joe says this alleged call never took place.
