BIRMINGHAM’S heavy metal legend Ozzy Osbourne is to be a grandad again.

His 25-year-old son Jack Osbourne has revealed that his actress fiancée is pregnant with their first child, less than two weeks after announcing their engagement.

The former TV reality star broke the news to CNN’S Piers Morgan, alongside Ozzy and his wife Sharon.

He said: “I’m excited. I’m a little nervous.”

When Black Sabbath star Ozzy, who was born in Aston, was asked about his feelings by Morgan, he said: “It doesn’t matter what I think, the baby’s on its way.”

Jack shot to fame through his family’s MTV reality show The Osbournes and has since appeared in several TV shows.

Earlier this year he produced a documentary about his rock legend father called God Bless Ozzy Osbourne

Ozzy’s other son, Louis, recently set up home in Harborne with his two children.
