Kelly Osbourne bought her father a birthday cake which "tasted like s**t".
The 31-year-old star treated dad Ozzy Osbourne to a belated sugar-free celebration following his 67th birthday last Thursday (03.12.15) because he has given up the sweet stuff - but the neither of the pair were big fans of the taste.
Kelly posted a picture on Instagram of the Black Sabbath rocker blowing out the solitary red candle on his cake, which was decorated with red and white icing.
She added the caption: "I finally got to celebrate my dads birthday with him! He no longer eats sugar so I got him a sugar free cake! We both thought it taste like s**t! (sic)"
Kelly's gesture came a day after her brother Jack Osbourne treated his father to a trip to family theme park Hersheypark in Pennsylvania, which sits adjacent to Hershey's Chocolate World.
Ozzy wrote on Instagram: "Had a great time with @JackOsbourne at Hershey Park earlier this week (sic)"
While Ozzy now lives a sugar-free life, eight years ago he couldn't get enough of glazed breakfast cereal Sugar Puffs and had a consignment shipped over from the UK to his mansion in Los Angeles.
A source said at the time: "One of the team at Honey Monster Foods received an e-mail with a request from Ozzy Osbourne's people in LA asking for them to ship over some boxes of Sugar Puffs.
"They said it was his favourite breakfast cereal and he was wound up because he couldn't find any over there."
