The youngest star of The Osbournes is now the proud dad to two little girls, after welcoming his second child over the weekend.

Jack Osbourne and his wife Lisa last night confirmed their new arrival, a baby daughter named Andy Rose.

Little Andy was born on Saturday weighing 6lb 11oz. The newborn will be a little sister for three-year-old Pearl, Jack and Lisa's first daughter.

Pearl seemed to be getting in the spirit of her mum's new arrival, posing for a photo earlier this week with a mini-bump of her own:

"She keeps putting baby dolls in her shirt…pretty sure she gets what’s happening here!" mum Lisa wrote on Instagram.

Jack and Lisa confirmed they were expecting a second child back in February. News of a new baby was especially precious given that Lisa suffered a miscarriage back in September 2013.

Lisa became pregnant with Pearl just one month into her relationship with Jack back in 2011, and the pair have been together since. They wed in a small ceremony in Hawa'ii a year later.

While Andy will be a second grandchild for Jack's mum Sharon, it will be the seventh for Ozzy, who has five grandkids by children from his first marriage, Jessica and Louis.

Sharon has spoken before about her love of being a grandmother, saying she will always be a soft touch with Jack's little ones. "You can spoil, you can indulge, and then say, 'Okay, now let your parents be the ones to teach you right from wrong. I'm not. What do you want? Have it!'" she said of life as a grandma.

Congrats to the happy parents… and grandparents!
