Well, you knew it was coming….Jessica Simpson’s father has been blamed for ruining her romance to Dallas Cowboys QB Tony Romo.

Romo split from Jessica last week – just a day shy of her 29th birthday — after reportedly became increasingly frustrated with Joe Simpson’s persistent meddling in his daughter’s private life.

The two had been dating since November 2007.

“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,” snitches told FOX News’ Pop Tarts column on Tuesday.

“At one point Joe was even giving Tony football advice which doesn’t go down well.”

In March, The National Enquirer reported that Joe – who also acts as Jessica’s manager – was jealous of Tony’s relationship with his daughter and believed it was to blame for the current state of Jessica’s once promising career.

“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.”

Sources close to Tony believe the football star has been losing interest in Jessica for some time.

“It was a long time coming, he hasn’t really been into her and the relationship for awhile, but stayed together because he didn’t want to look like a jerk for not having a better reason to break it off,” one insider remarked sadly.

“She is trying to save face by saying that it’s because of their busy schedules.”
