Sports star Tony Romo allegedly called off his romance with Jessica Simpson after growing tired of her meddling father, according to a new report.

A friend who attended Eastern Illinois college with Romo, claims the American football quarterback and the pop star "are definitely over" - despite Simpson's representatives insisting the duo are still an item.

And the source - who was reportedly with Romo while he partied with a bevy of beauties at a Chicago, Illinois bar at the weekend - claims her overbearing father, Joe Simpson, was one of the major factors in their split.

The unnamed pal tells the Chicago Sun-Times that Joe Simpson had been "not only telling Jessica every move to make, but now has begun to offer unsolicited advice to Tony on his career, endorsement opportunities and things that have nothing to do with him dating Jessica."
