Ozzy and Sharon are getting another grandchild! Jack Osbourne and his wife Lisa are expecting their second child together. The Dancing With the Stars season 17 alum announced the news via Instagram on Saturday, Feb. 21.

"Supprise!!!!! #round2 #babyinbound," Osbourne, 29, captioned a photo of his wife and the couple's daughter Pearl, 2. Stelly showed off her bare baby bump in the pic as Pearl smiled while giving her mom a hug.

Lisa also revealed she was expecting again on her blog Raddestmom.com. "I'm pregnant! Pearl is very happy to become a big sister," the 27-year-old wrote. "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!" she gushed. "Thanks for all the well wishes."

The couple dated for a year before tying the knot in October 2012. The baby news is extra special for Lisa, who sadly suffered a late-term miscarriage back in 2013.
