Jay Cutler engaged

Jay Cutler had other things on his mind this past week besides the NFL's uncertain labor situation.

The Chicago Bears quarterback became engaged to reality-TV star girlfriend Kristin Cavallari over the weekend during a romantic getaway in Cabo San Lucas. She tweeted the news Thursday which was first reported by People.com this week.

"I can finally tell everyone that IM ENGAGED!!!!!" Cavallari announced Thursday on her Twitter account, @KristinCav. She said she appreciated "all the sweet messages from my fans."

Cavallari, 24, who has appeared on hit reality show "The Hills," and Cutler, 27, have been dating since the fall.

"He surprised her with a quick trip to Cabo to ask her to marry him," a source close to the couple said, according to People.com.
