Anticipating the arrival of his first child in just a few weeks, the son of Sharon and Ozzy Osbourne took his BabyBjörn child harness for a test drive – with a little help from a canine friend.
"@MrJackO testing out the baby Bjorn last night!" his fiancée, actress Lisa Stelly, Tweeted on Jan. 19, with a shot of her man holding French bulldog Bruce in an infant carrier.
Though he told Piers Morgan last year that he was nervous about fatherhood, Osbourne now seems to be fully engaged – even attending a third trimester appointment with Stelly on Jan. 11.
"Going to the baby Dr with @lisamarstelly," he Tweeted. "I get to see how much this little critter has grown. Not long now before a new osbourne arrives!"
