"Supprise!!!!! #round2 #babyinbound http://raddestmom.com/" Osbourne posted on Instagram Saturday, alongside a photo of their 2-year-old daughter Pearl with her head resting on his wife's baby bump.
"I'm pregnant! Pearl is very happy to become a big sister. She diligently reads her "I'm a big sister" books every night & recites to me her plans of bathing, feeding, singing to, and holding the baby. We are more than halfway through this thing & are very excited to be parents again! Thanks for all the well wishes," Stelly wrote on her website.
The couple married in October 2012 after dating for a year. Osbourne is the son of The Talk co-host Sharon Osbourne and the rock icon Ozzy Osbourne. Fashion Police panelist Kelly Osbourne is his sister.
