Putting their romance on the fast track, Kristin Cavallari is ready to tie the knot with her NFL star beau Jay Cutler!

The former "Hills" star was popped the question by her Chicago Bears quarterback husband-to-be over the holiday weekend during a trip to Cabo San Lucas, Mexico.

An insider tells People magazine, "He surprised her with a quick trip to Cabo to ask her to marry him. He had asked her dad for permission."
