It is very bad for a woman to be dumped by her boyfriend. But it is doubly bad when the dumping happens on the woman's birthday eve. This is what happened to Jessica Simpson, her boyfriend Tony Romo dumped her the day before her birthday.

Here's a little about it from People.com:

Tony Romo broke up with Jessica Simpson on Thursday, the night before her 29th birthday, a source close to the pop star tells PEOPLE.

"She is heartbroken," says the source. "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."

The Dallas Cowboys quarterback fueled breakup rumors when he showed up with about 14 friends at the Hollywood hotspot MyHouse on Friday night without the birthday girl, a source tells PEOPLE.

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

Simpson’s rep had no comment. Romo's rep could not be reached for comment.
