Former Laguna Beach star Kristin Cavallari got one sweet surprise while on vacation in Mexico with her NFL beau Jay Cutler.
A source close to the couple confirms to PEOPLE that Cutler proposed over the weekend during their getaway in Cabo San Lucas.
"He surprised her with a quick trip to Cabo to ask her to marry him," the source says.
Cavallari, 24, who also appeared on The Hills, and Cutler, 27, the quarterback for the Chicago Bears, have been dating since last fall.
"I'm in love," she told PEOPLE earlier this year, "and it's been great."
Her rep couldn't be reached for comment.
