While Tony Romo is reveling in his renewed membership to the Singles-R-Us Club, Jessica Simpson is having a hard time coming to grips with being dumped a day before her 29th birthday, people.com reports.

“Jessica was really blindsided,” says a Simpson family friend. “She’s sad, mad, and confused. Her emotions are all over the place.”

Another source close to Simpson tells People that “it’s been difficult lately” for the pair, who first started dating in November, 2007.

“Dating her comes along with her celebrity and press — that’s not easy for anyone,” says Simpson’s family friend. “But she and Tony seemingly had it figured out. They rolled with the punches and focused on each other. They just lost sight of that at the end.”

Since the sudden split, Simpson has been laying low. “She is holding up OK,” says the Simpson source.
