Jack Osbourne and his wife Lisa Osbourne are expecting another baby.

Jack, a seventeenth-season Dancing with the Stars contestant, is expecting his second child with Lisa and announced the news on Instagram Saturday.

"Supprise!!!!! #round2 #babyinbound," Jack, 29, captioned a photo of his pregnant wife and their two-year-old daughter Pearl.

Pearl was hugging her mother's baby bump in the picture and both girls were smiling ear to ear.

Lisa, 27, also shared her thoughts about the new baby on her blog Raddestmom.com.

"I'm pregnant!" she wrote in a Saturday post.

"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."

Jack, who was diagnosed with relapsing multiple sclerosis in 2012, and Lisa wed in October 2012 after dating for one year. Lisa unfortunately suffered a late-term miscarriage in 2013, so the parents are clearly overjoyed, according to Us Weekly.

Jack first became famous when he appeared on his family's reality show The Osbournes on MTV.
