Jack Osbourne and Lisa Stelly

Jack Osbourne and wife Lisa Osbourne recently welcomed their second child.

The 29-year-old television personality confirmed the news Wednesday on Instagram after Hello! magazine reported Lisa Osbourne gave birth to daughter Andy Rose on Saturday, June 13.

"This is how you celebrate when Mum is breastfeeding and Dad is sober. Thank you all for the kind words #newbaby," he captioned a photo of two glasses and a bottle of sparkling cider.

Osbourne and his wife welcomed their first child, daughter Pearl Clementine, in Apr. 2012, and married in Hawaii in October of that year. The couple revealed they lost a son in Sept. 2013.

"Pearl is very happy to become a big sister," Lisa Osbourne wrote on her blog in February. "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."

Jack Osbourne is the youngest child of Ozzy Osbourne and Sharon Osbourne, and brother to Kelly Osbourne and Aimee Osbourne. He starred on MTV reality series The Osbournes from 2002 to 2005, and was diagnosed with multiple sclerosis in 2012.
