          Rare photos of Sharon and Ozzy Osbourne's 5 grandchildren

          They're one of the most famous couples ever thanks to their hugely successful careers in music and entertainment, so the world got to know Sharon and Ozzy Osbourne's children pretty well when the family fronted the iconic reality TV show, The Osbournes.

          But Sharon, 72, and Ozzy, 75, are now proud grandparents as their children have grown up and started families of their own.

          The former X Factor judge and the Black Sabbath frontman share Aimee, 41 – who opted out of appearing on the famous MTV show – Kelly, 40, and Jack, 38.

          Their youngest kids, Kelly and Jack, are now parents themselves, making Sharon and Ozzy grandma and grandpa.

          Ozzy is also a dad to his two children, Louis and Jessica from the musician's first marriage to Thelma Riley, though it's not known if his eldest two have any children as they mostly stay away from the spotlight.

          As for Jack and Kell
