Kristin Cavallari isn't inviting any of her former castmates from The Hills to her upcoming wedding.

The reality TV star - who is set to tie the knot with Chicago Bears quarterback Jay Cutler this summer - wants a small, intimate ceremony and says there is no room on the guest list for her old co-stars Audrina Patridge, Stephanie Pratt or Heidi Montag, but insists it isn't because she doesn't want them there: "It's going to be family and really close friends. If the wedding were bigger, I would have loved to invite Audrina, Stephanie and Heidi. It's going to be perfect. We're ready to be together for the rest of our lives."

Kristin recently revealed she was fully prepared and ready for her big day. "Everything is planned and ready to go, but that's all I'm going to tell you," she said.

The couple welcomed their first child Camden into the world in August 2012 and the blonde beauty can't wait to have more children as they are really enjoying watching their son develop: "It's a lot of fun. Yeah, we want a bunch of kids. He's doing amazing. He's great. He's six months old now, which is crazy how fast everything flies by. He has his two bottom teeth. I think he's teething and getting another one, and he's eating food. He's just laughing and smiling all the time, he's so much fun."
