Jack Osbourne to become a dad

Los Angeles - Jack Osbourne is to become a father for the first time.

The Adrenalin Junkie star has confirmed fiancée Lisa Stelly - who he got engaged to two weeks ago - is expecting their first child and he can't wait to be a dad.

During an appearance on CNN's Piers Morgan Tonight with his parents Ozzy and Sharon Osbourne, he revealed: "My life is absolutely insane right now. I guess technically I do have something to tell you. I'm about to be a father. I'm excited. I'm a little nervous, but I'm excited. It's going to be fun."

Jack shot to fame on family reality TV show The Osbournes but the 25-year-old star has vowed not to put his own offspring through the same experience.

He said: "I'm not going to do a reality show, though!" 

Grandma

Ozzy and Sharon are equally as thrilled by the news, though the heavy metal legend admits he is still in "shock".

He joked: "I'm in shock. It's fantastic. It doesn't matter what I think - the baby's on its way."

Sharon added: "I'm happy because it's what Jack wants. And so I'm happy and I've always wanted to be a grandma." 

Meanwhile, Jack's sister Kelly proclaimed herself to be the "luckiest girl in the world" about the news.

She wrote on her twitter page: "girls night in w/ @lisamarstelly my future sister in law & mother of my niece/nephew we are so happy the news is out so i can talk about it
