She may have been reality TV’s resident man-eater on both “Laguna Beach” and “The Hills,” but it seems that Kristin Cavallari is ready to settle down.

The small-screen star and her beau, Chicago Bears quarterback Jay Cutler, are engaged, according to People. A source told the website that Cutler asked Cavallari to marry him while on vacation in Cabo San Lucas, Mexico.

“He surprised her with a quick trip to Cabo to ask her to marry him,” the source said.

The pair have been dating since last fall. Cutler reportedly gave Cavallari a 5.2-carat engagement ring and he’s wanted to propose for some time.

Cavallari gushed about her feelings for Cutler at her 24th birthday in Las Vegas in January, insisting, “I’m in love and it’s been great.”
