Jack Osbourne is to become a dad for the first time, after it was revealed his fiance Lisa Stelly is pregnant.

The 25-year-old announced the news to Piers Morgan while on his CNN Tonight show.

After revealing the news, Jack was joined on the show by his parents rocker Ozzy and former X Factor judge Sharon.

He told Morgan that he was "excited" and "a little nervous".

His mother has also had her say on the impending new arrival, telling US TV show The Talk that she will spoil her first grandchild:

"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!'"

Jack and Lisa had been dating for four months before announcing their engagement.

Stelly took to Twitter to share the news of the proposal, posting:

"The most amazing man I've ever met asked me to marry him... and he wasn't joking! Crazy, right :)."
