They were the big bad wolves in The Hills but that's all behind them now as Spencer Pratt and Heidi Montag want to start a family.

Heidi recently spoke to Faithwire and revealed: "I am writing a coffee table wife type of book, it is more like a fun project, something I enjoy doing and then I am getting ready to be a mom hopefully next year.

"So that is going to be my main priority and full-time job."

The pair have remained in the spotlight since starring in The Hills and tied the knot in 2009.

Imagine Spencer being a dad!
