Sharon and Ozzy Osbourne's daughter took to Instagram on Saturday to show fans her new hairstyle.
"#SomeonesGettingANewLook," posted the 29-year-old with a picture of the locks that had been removed lying in a pile on the floor, before revealing the new look itself.
"What do you guys think?" wrote Kelly next to the photo, which quickly garnered more than 30,000 likes. "@linocarbosiero has been cutting my hair for 29 years! @hairbylino!"
Several days earlier Kelly had hinted that her hair was about to undergo a change when she posted a picture of her mother's dog wearing a wig.
"#BitchStoleMyLook," she joked. "My mums dog Bella really needs to stop it!"
Bride-to-be Kelly, who announced her engagement to vegan chef Matthew Mosshart in July, has been enjoying Christmas in England this year.
The Fashion Police presenter, who was born in London but lives in LA, spent the festive season in the British countryside.
"Been duct taping windows & emptying pans of water since 5pm all the antique windows in our house are leaking! #StormEmily please stop!" She tweeted. "I know they say it always rains in England but this is next level!!!!!!"
"I have been woken up every day by wild parakeets cheeping!" Wrote Kelly in another post. "Can someone please explain how they got to the British countryside?"
