Adding insult to injury, Tony Romo not only has ended his relationship with Jessica Simpson, but the split reportedly happened the day before the pop singer’s 29th birthday.

A source dished to Us Weekly that Simpson has canceled her Ken and Barbie-themed birthday bash as a result, but is “doing OK.” In addition, a friend of Romo’s said the break up didn’t come as a shock. “They go from one fight right into another, without a second break,” the snitch tattled.

With the festivities canceled, Romo opted to spend his ex-girlfriend’s birthday at the L.A. club My House. As a fan of the Newlyweds series, I can only hope it’s no coincidence that both Jessica and her ex-husband Nick Lachey are single at the same time. Lord knows, they were much stronger with their powers combined.
