Sharon Osbourne has revealed that she can't wait to spoil the new addition to the family – but that her first grandchild won't be calling her grandma.
Sharon and Ozzy's son Jack, 25, who has been dating model fiance Lisa Stelly for less than five months, has announced that the young couple are having a child.
The former X Factor judge, 59, said she can't wait to be a grandmother, but added on TV show The Talk: "The baby's going to have to call me Shazza or Mrs O.
"In London, that's Sharon, the abbreviation is Shazza. They call you, 'Shazza.' 'Hello Shazza!'
"Our family is growing, and I love that. It's just a blessing, it's a joy. They're going to have a baby in April," she added.
And mother-of-three Sharon is looking forward to indulging her grandchild, revealing she will let the baby get away with "everything".
"That's what comes with being a grandmother. 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!' "
Sharon said Jack was already "so excited" about becoming a father.
"It was just overflowing from him... His eyes were all teary," she said.
