In an exclusive interview with In Touch, Jillian opens up about the stress of wedding planning and why she thinks she and fiancée Heidi will end up at City Hall.

“I think we’re going to end up in jeans and T-shirts at City Hall,” she adds with a laugh. "And then maybe spend the money we saved on a great honeymoon!”

Jillian gushes about her two kids, explaining that they are doing “great.”

“With Lukensia, I have a permanent helper. My son, meanwhile, is testosterone in action. He’s been watching the Ninja Turtles, and you walk around the corner and get attacked by a tornado with plastic nunchucks.”
