Actress and reality TV star Kristin Cavallari is preparing for her next role -- blushing bride!
The former Laguna Beach star, 24, reportedly got engaged to her NFL beau Jay Cutler, 27, while the couple vacationed in Mexico over the weekend.
A source close to the couple confirmed to PEOPLE that Cutler, a quarterback for the Chicago Bears, popped the question during their getaway in Cabo San Lucas.
"He surprised her with a quick trip to Cabo to ask her to marry him," the source told PEOPLE.
Cavallari has been open about her relationship since the two began dating last fall. On Friday, she tweeted, "Cabo with my man."
No word on when the two will walk down the aisle.
