Forget about The Hills, Kristin Cavallari is proving to be quite the stunner all over the world. And today, Jan. 5, she celebrates her 25th birthday. It has been a crazy year for Kristin, who starred on Dancing With the Stars, and got re-engaged to her football star beau, Jay Cutler.

Well, here's to a great year ahead. Leave a birthday message for Kristin in the comments and celebrate her big day by checking out her sexiest bikini pics.

Her engagement to football star Jay Cutler is back on, and she's more in love than ever. "Sometimes, in order for things to get better, they have to end – even if it's momentarily. And that was the case with us," she told People.

The couple split back in July after becoming engaged in April. Despite being apart, Kristin reveals they were still very much in love and talked every day.

"We didn't break up because of love lost. We loved each other just as much as we always did when we weren't together," she said, while staying mum about when the two will eventually tie the knot.
