Jessica Simpson and Tony Romo are back on — but under one condition.
Her notoriously controlling father Joe needs to stay away.
A pal from Romo's Eastern Illinois University tells the Chicago Sun-Times that the Dallas Cowboys quarterback "did agree to go to [sister Ashlee's] wedding -- keeping his promise to Jessica, but he made it super-clear that if they were to give it another go, her dad had to seriously back off."
Their relationship, the pal added, is "a trial thing," depending on Joe "leaving them alone" and not trying to manage Romo's life, career and endorsement deals.

Split rumors surfaced the week that Ashlee got hitched. Pete Wentz refused to comment on them, telling Ryan Seacrest, "I don't know anything about what's going on with them."
Romo was noticeably absent from a recent trip to Cabo San Lucas, Mexico, that the singer took with her parents. While leaving the airport, she was photographed wearing a Dallas Cowboys cap, suggesting a reconciliation.
