On the heels of his recently announced engagement, Jack Osbourne will confirm on this evening’s Piers Morgan Tonight that he and fiancée Lisa Stelly are expecting their first child together, reports People. Jack sat beside his parents Ozzy and Sharon Osbourne, who will be first-time grandparents, for the interview. They both expressed unreserved support and excitement, as did Jack’s sister Kelly, who tweeted the baby news late last night.
