Pop star Jessica Simpson and American footballer Tony Romo have ended their relationship, according to U.S. reports.
The Dallas Cowboys quarterback sparked fresh break-up rumours when the singer was noticeably absent from an entourage of pals who joined him on a night out in Hollywood on Friday (10Jul09), Simpson's 29th birthday.
According to People.com, Romo ended the pair's relationship one day before (09Jul09) - just four months after the pair fought off rumours of a split amid reports Simpson's father disapproved of their relationship.
A source says, "He had quite a few girls stop by his dance floor table. Romo was sipping Grey Goose and having a fun time with the boys.
"She is heartbroken. She loves Tony. But it's been difficult lately. He's busy with his career and she's getting ready to shoot her show (The Price of Beauty). They decided to part ways."
Simpson, who was previously married to singer Nick Lachey, has been dating Romo since November 2007.
A spokesperson for Simpson had no comment as WENN went to press.
