Jessica Simpson and longtime boyfriend Tony Romo called it quits on Thursday, the day before Jessica's 29th birthday, according to 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.
Simpson had planned to throw a Barbie and Ken-themed party for her birthday, but it fell through, according to a message she wrote on her Twitter page Saturday. "Barbie party didn't happen, but I turned 29 and feel like I am on top of the world yelling I LOVE GETTING OLDER!" she wrote.
