Jack Osbourne has adapted to being a daddy, putting aside his hard-partying ways.

The 27-year-old rock ‘n roll heir and reality star married Lisa Stelly in October 2012, six months after the birth of daughter Pearl, and he admits he is no longer interested in wild nights out, telling People, "Getting married and having a child definitely has focused me.

"Now I'm not so much worried about going out on a Tuesday night and staying up until three in the morning and meeting hot chicks. No."

While Jack and Lisa are adjusting to being parents, he says his mother Sharon and father Ozzy are also having to adapt to having Pearl around, though they play a big role in Pearl’s life.

"Nanna and Grandpa are busy, but they're very involved,” he says.

"Every Sunday we have lunch together [...] It's taken me nine months to really hammer into them that driving all the way across town with a newborn baby is a lot more difficult than them driving all the way across town to visit me and a newborn baby. And they're starting to actually understand that now!"
