Kristin Cavallari's fiance says she is completely in charge of planning their wedding.

The former 'Hills' star rekindled her romance with NFL player Jay Cutler in September following their July break-up and Jay revealed he is happy with however his future bride wants their nuptials to be.

Speaking on Chicago's Waddle & Silvy ESPN radio show, he said: "I don't really make a lot of [wedding] decisions.

"I hear about them in passing or if I have to possibly pay for something or something like that, but other than that, whatever she wants to do, I'm on board."

Joking that he's "just kind of along for the ride," Jay told the show's hosts that they are "asking the wrong person" when it comes to knowing about the date or location of the wedding.

Meanwhile, a close pal revealed the pair are happier than ever since getting back together.

The source told People: "Things have been going really well. They're happy together. They just now understand each other a lot better. He understands what she needs and she totally supports him. They're there for each other."
