Kelly Osbourne has been attacked by a bat in Australia, 34 years after her rocker father Ozzy's headline-grabbing bat-biting concert stunt.

The Black Sabbath frontman went down in the rock 'n' roll history books when he was accused of biting the head off a live bat during the band's gig in Des Moines, Iowa on 20 January, 1982, but he later insisted he thought the animal was a rubber toy.

Now Osbourne's daughter Kelly had her own brush with a winged mammal after she was attacked by a bat in Sydney, Australia.

The reality TV star, who is in the city filming Australia's Got Talent, took to social media to tell fans about the terrifying incident, during which a bat swooped on her while she walking to a local pie shop.

Kelly claims the animal "attacked" her and defecated on her head, and she shared a picture of the mess in her hair as proof.

She added in a caption on Instagram.com, "walked down the street to @harrysfamouspies where a... bat attacked me and (pooped) on my head!"

Rock veteran Ozzy previously had his own problems with bats when a colony took up residence in a barn he planned to renovate as "karma" for his notorious stage stunt.

Ozzy was stunned when he found out the creatures, which are protected in the U.K., were living in the roof of the building on his estate in Buckinghamshire, England as they effectively scuppered his plans to convert the barn into a two-bedroom home.

He later insisted it was payback for the bat-biting stunt, telling Britain's Event magazine, "I laughed my head off when (wife) Sharon read out the letter (from officials about the bats)... I said: 'They're vermin - I'm going to shoot them.' But I know it's funny. It's actually really cool. Karma's going to bite you... The bats... won."
