Kristin Cavallari [1] took to Instagram on Saturday to share big news about her growing family: she and husband Jay Cutler are expecting a second son [2]. Kristin wrote in the caption, "We couldn't be more excited!" The couple discovered the sex of their baby over the holidays, but until now, have remained tight-lipped. “Of course, I want a little girl, but another boy would be a ton of fun, too, so I really don’t care either way,” she told People magazine last year. Their son, Camden Jack, will become a big brother when Kristin gives birth this Spring.
The designer and former Hills star has showed off her baby bump in a series of social snaps since her pregnancy announcement [4] in October. In one selfie, Kristin's bump was front and center during a trip to the gym. Her guys are also working on their fitness — Jay and Camden played a father-son game of basketball in a pic she shared on Saturday. Congratulations, Kristin, Jay, and Camden!
