Watch OZZY OSBOURNE's Granddaughters Sing Along To 'Crazy Train'

Jack Osbourne took to his Instagram over the weekend to post a video of his daughters — Andy Rose, 3, Pearl Clementine, 6, and Minnie Theodora, 13 months — performing "Crazy Train" for their grandfather, Ozzy Osbourne.

Ozzy's wife and Jack's mother, Sharon Osbourne shared the clip on Tuesday's (March 19) episode of her CBS daytime talk show "The Talk".

"Did you see the way Andy sneaks in. She starts the headbanging," said Sharon. "They did that to make their papa feel better." Co-host Sara Gilbert added, "No question, those are Osbournes."

Andy, Pearl and Minnie's mother is Lisa Stelly, whose divorce from Jack was finalized earlier this month.

Stelly filed for divorce from the 33-year-old in May 2018 after nearly seven years of marriage.

After news of the divorce broke, Jack shared a statement to Instagram addressing their split, writing, "So the news about us separating has probably come as a bit of a shock to everyone. But we just want to clear the air and share with you what's going on.

"First and foremost, we absolutely still love each other," the statement continued. "Our family is the most important thing in our lives, and we tried everything we could for many years to make this work. What's best for our family right now is that we separate lovingly, and remain best friends who are committed to raising our children together."

Last September, Sharon said that she was "very, very sad" about her son's divorce. "She's a good girl," Sharon told "The Howard Stern Show". "And the thing is it just didn't work. They love each other, [but] they can't live with each other."

Jack and Lisa married in 2012 and experienced a late-term miscarriage in 2013. The couple have faced other hurdles, including Jack's multiple sclerosis diagnosis.

Before getting engaged, Jack and Lisa had been dating for only four months, according to Britain's Daily Mail.
