Ozzy Osbourne doesn't understand why the Kardashians are so famous.
The Black Sabbath rocker admitted he asked his wife Sharon to explain the phenomenon to him, as he suggested the reality TV family - which includes social media queen Kim Kardashian West and model Kendall Jenner - "don't do anything" to justify the attention they get.
Speaking to The Big Issue, he said: "I said to Sharon the other day, 'What the f**k is the deal with these Kardashians? They don't sing, they don't act, they don't do anything.'
"She told me, 'The trend now is that people want to be celebrities and make money for doing f**king nothing.' And I was like, 'Oh.' "
Despite his comments, the 69-year-old musician wished the 'Keeping Up With The Kardashians' clan luck and admitted all that matters is that they're "happy" with their career and lives in the spotlight.
