Sharon Osbourne Reveals Son Jack Obsourne is Expecting a Baby [VIDEO]

On yesterday's episode of 'The Talk,' Sharon Osbourne excitedly announced that she's about to be a grandmother for the first time. Osbourne's son Jack is expecting a child with fiance Lisa Stelly in April.

But, as you might have guessed, Osbourne probably won't be a typical nana. Instead of being called "Grandma," for example, she demands that the child call her "Shazza" -- British slang for "Sharon" -- or "Mrs. O."

Check out Osbourne's announcement below and a separate clip from 'The Osbourne' featuring a much younger Jack arguing the virtues of the McRib. (Sniff!) How quickly they grow up!
