Ozzy Osbourne’s Grandson Bites Off Bat’s Head in Adorable Halloween Video

Kelly Osbourne‘s son is showing the apple doesn’t fall far from the tree … biting the head off a “bat” in an adorable new video.

Kelly took to TikTok to show her infant son, Sidney, dressed as a skeleton … where he’s seen taking a big bite out of a stuffed bat before ripping its head clean off.

Sidney’s clearly proud of his work … flashing a big smile and laughing once the head’s clean off.

Fittingly, Kelly set the moment to Ozzy‘s classic hit “Crazy Train.”

Of course … you’ll recall the legendary rocker infamously pulled off the shocking stunt during a 1982 performance — though he didn’t realize it was a real bat at first.

Kelly captions the clip … “Learned from the greatest, Papa!”
