Jack Osbourne To Be First Time Dad

Jack Osbourne has announced that he and fiancee Lisa Stelly are expecting their first child.

Appearing on Piers Morgan Tonight with parents Sharon and Ozzy last night, the TV personality revealed the news for the first time.

He said "I'm excited. I'm a little nervous, but I'm excited. It's gonna be fun. I'm not going to do a reality show, though!"

When questioned by Piers, Ozzy admitted he is "in shock", adding "I think it's fabulous". He already has four grandchildren through Jessica and Louis, who he fathered with first wife Thelma Riley.

Sharon will be a first time grandmother, and said she has "always wanted to be a grandma".

Joking that he will tease his America's Got Talent co-star on being a grandmother, Piers said "Jack - you have made my decade."

Jack and Lisa announced their engagement last month, after dating for under a year. Sister Kelly has been voicing her approval, saying Stelly is the only one of Jack's girlfriend's she's ever "actually really liked and not had to pretend to like".
