Family planning works! Former 'The Hills' reality star Kristin Cavallari is pregnant again, expecting her second child with her QB hubby Jake Culter of the Chicago Bears.

Looks like Jessica Simpson isn't the only one reproducing at a rapid clip!

E! was the first to report the good news.

Cavallari and Cutler welcomed son Camden in August of 2012. The couple wed in Nashville a little under a year later -- in June 2013. Now, they are expanding their family and it wasn't an accident.

In September, the onetime MTV personality, 26, told E! that she and her NFL hubby were "working on it" and that "we want to have a second sooner than later," since "we know we want another one close in age to Camden and we're at the point where we're both ready. Before Camden was born, I thought I'd be pregnant again by the time he was six months, but I definitely wasn't ready. Now, I'm finally ready."

Cavallari is hoping for a sister for Camden, but she'd be equally thrilled with a brother, too. "If I had another boy I would be so excited as well," she said. "I love having a boy. Either way, I'd be really, really happy."

Congrats to the duo!
