HOLLYWOOD, Calif. — Jessica Simpson and Tony Romo are finished.
According to sources, the Dallas Cowboys quarterback dumped Simpson last Thursday, the night before her 29th birthday.
"She is devastated," said an insider close to Simpson. "They've had their share of ups and downs, but she was still wildly in love with him."
Speculation about the couple's future kicked into high gear when the 29-year-old Romo showed up alone Friday night at the Hollywood hotspot MyHouse. Simpson had planned to spend her big day having a Barbie and Ken-themed birthday party.
"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 Tweeted on Saturday.
Simpson and Romo started dating in November 2007 and have long endured breakup whispers. Last summer, Romo's ex-girlfriend, singer Carrie Underwood, created a controversy when she claimed that the football star was still calling her in an interview with Allure.
"It was just something that was said in passing," the country star later said. "I would never mean to say anything to hurt anybody or to stir up anything because I'm just not about drama — at all."
Underwood's suggestion that she was still hearing from Romo prompted a quick response from Simpson.
"Tony and I both laughed at that," Simpson quipped while appearing on Nashville's 107.5 FM's Woody and Jim show. "We got a chuckle out of it."
Simpson later tried to downplay that there was any bad blood between her and Underwood, saying she wasn't taking a shot at the vegetarian country star when snappers captured her wearing a "Real Girls Eat Meat" T-shirt.
"I wore it because I thought it was funny," Simpson explained. "I did not know that she was a vegetarian. It's definitely not a diss on her by any means."
Despite their ups and downs, Simpson, who was previously married to singer Nick Lachey, often praised Romo for being different than her past boyfriends.
"I'd always fall for guys I wanted to save," Simpson said in the December issue of Cosmopolitan. "For the first time, I fell in love with someone who saved me."
Reps for both stars have yet to comment on the split.
