Despite all the breakup talk, Jessica Simpson and Tony Romo are back together, but a college friend of the Dallas Cowboys quarterback says Romo's insisting on calling the plays from now on.

"He did agree to go to [sister Ashlee's] wedding - keeping his promise to Jessica," Romo's Eastern Illinois alum pal told the Chicago Sun-Times.

"But he made it super-clear that if they were to give it another go, her dad, Joe, had to seriously back off."

Joe Simpson, a former minister and current pimp, has long been seen as an overbearing presence, managing both his daughters' careers.

While clearly successful at what he does - look at how much money he's made off two airheads with no talent - Joe Simpson has earned a reputation as a guy who's, um, extremely difficult to work with.

The Sun-Times says Tony Romo told Jessica Simpson that their renewed relationship is on a trial basis, so long as Joe "leaves them alone" and stops telling Romo how to run his life, career and endorsement deals.

Tony Romo and Jessica Simpson have been seen together in recent days, after the solo vacation Jessica took in Cabo San Lucas following the pregnant, talentless Ashlee Simpson's marriage to Fall Out Boy's Pete Wentz.
