Jack Osborn, and fiancee Lisa Stelly welcome a baby GIRL today!! "Pearl" Osborne is the first grandchild to rocker Ozzy Osborne and wife Sharon. They are excited to say the least:

“I’m going to be the grandmother from hell, because I am going to spoil this baby so bad,” she said. “My son and Lisa are going to be like, ‘Get her out of here!’”  (celebritybabies.people.com)

Pearl weighed 8lbs 6oz at birth. Congratulations to the 'rockin' happy family!
