Ozzy Osborne is a Grandpa for the sixth time and the first time all at the same time.

Ozzy's son, Jack and his fiance Lisa Stelly had a baby girl on Tuesday. A source told People Magazine the couple named the little lady Pearl and she weighed in at eight pounds, six ounces. Proud Grandmother Sharon Osborne tweeted, "Today I witnessed my first grandchild being born, life changing experience. She is an angel." Ozzy already has five grandchildren from his first marriage to teacher Thelma Riley, but this is his first grandchild with Sharon.

No word on a wedding date for Jack and Lisa. It's hard to believe that the bespectacled kid with the braces and a perm that we saw on The Osbornes on MTV is a dad, but a big congratulations to them all. By the way, Mom, Dad and baby Pearl are all doing fine.
