Kristin Cavallari, Jay Cutler expecting 2nd baby

Kristin Cavallari and her Chicago Bears quarterback husband Jay Cutler are one step closer to having their own football team.

Cavallari is pregnant with their second baby. The 26-year-old former star of MTV's ''Laguna Beach'' and ''The Hills'' confirmed the news Wednesday on Twitter. She wrote: ''We are so excited for Camden to be a big brother!''

Camden is the couple's 14-month-old son.

Cavallari and Cutler were married last June in Nashville, Tenn.

The family splits their time between Nashville and Chicago.
