London, October 31 : Sharon Osbourne, who is about to become a grandmother, refuses to be called `granny' and would prefer `Shazza' instead.

Her son Jack's fiancée Lisa Stelly is expecting in April.

"She wants to be called Shazza, not granny - but it sounds like a smoky old barmaid!," the Sun quoted Jack as saying.

It will be the first grandchild for former X Factor judge Sharon and her Black Sabbath rocker hubby Ozzy.

"Our family is growing and I love that. It's just a blessing - a joy," the 59 year old says. (ANI)
