Ozzy Osbourne is a big softy when it comes to his grandchildren. In an Instagram post shared by his son Jack Osbourne on Sunday, the 'Prince of Darkness' can be seen doing some arts and crafts with Jack’s daughter, Pearl. Check it out above.

This isn’t the first time the singer has been caught being cute with his fifth grandchild, Pearl. Back in October Ozzy told 97.1 The River about being her grandfather, "Pearl is such a great experience to have. I have other grandchildren, but when I had my own kids, I was touring or in rehab. It's a lot better environment now. I can be of service to my family."

The pair obviously have a great relationship, and Pearl even dressed up as 'The Princess of Darkness' for Halloween in 2013. Meanwhile, Jack and his wife Lisa are expecting another child this year.

From toddlers and cartoons to animation and videos, we have more Ozzy goodness for you. Radio.com has created an animated video clip taken from the archives of N.Y. radio station WNEW-FM. In the video, the singer explains how they came up with the musical direction for Black Sabbath. Ozzy says guitarist Tony Iommi thought of experimenting with spine-chilling material while rehearsing near a movie theater that was playing a horror film. “One day, Tony says, ‘Don’t you think it’s strange that people pay money to go and get scared to death at horror movies?'” The rest is heavy metal history. Check out the clip below.
