Kristin Cavallari, Jay Cutler end their engagement

Kristin Cavallari and Chicago Bears quarterback Jay Cutler have called off their engagement, multiple sources said Sunday and Monday.

OK, one source told it more specifically: "She got dumped," People heard. "She's absolutely devastated. She can't believe this is happening."

Meanwhile, in Cutler's circles, folks couldn't believe the end of the NFL lockout was happening. But that's another story.

The breakup news first came via Access Hollywood, which also reported the dumpage angle. The 24-year-old TV personality known for "The Hills" and "Laguna Beach" was celebrating her engagement a week ago with a party, shortly after the couple's gift registries went public.

Then Saturday night, People said, Cavallari was seen out at a club in L.A. sans ring, telling the likes of Nicky Hilton and Alessandra Ambrosio that it was all over with the 28-year-old jock.

Cavallari and Cutler had been dating since last fall, and got engaged in April.
