Jessica Simpson: Dumped By Tony Romo!

Tony Romo broke up with Jessica Simpson Thursday, according to reports.

The alleged actress turned 29 the next day. Happy birthday, Jessica!

"She is heartbroken," says a People source. "She loves Tony. But it's been difficult lately. He's busy with his football career and she's getting ready to shoot her reality show (The Price of Beauty). They just decided to part ways."

The Dallas Cowboys QB fueled breakup rumors when he showed up with about 14 friends at Hollywood hotspot MyHouse Friday without the birthday girl.

"He had quite a few girls stop by his dance floor table," says an onlooker. "Tony Romo was sipping Grey Goose and having a fun time with the boys."

Jessica Simpson had planned to throw a Barbie and Ken-themed party for her birthday, but it fell through, according to a post on her Twitter page.

"Barbie party didn't happen, but I turned 29 and feel like I am on top of the world yelling I LOVE GETTING OLDER!" the aspiring singer Tweeted.

The source says Simpson is sad they broke up. "They were good together for along time," says the source. "But I guess it wasn't meant to be."

Still, Romo tried to dump her before and that didn't take, so there is always the chance they'll get back together. "They go from one fight right into another, without a second break," the source says. "It's always something with Jessica."
