Ex Blur star Alex James has admitted he hasn't washed his hair for 10 years.
Alex, 47, who now lives in the Cotswolds and makes his own cheese, said he was not "fussed" about his locks.
The Britpop star was quoted as telling Living magazine that he only washed his hair last week after his daughters decided to cover his mop in grey hairspray to mark Halloween.
"My hair isn't really something I've ever particularly thought about or fussed over," he reportedly said.
"Other than this week when both my daughters were keen to give me a Halloween makeover and emptied a whole can of grey-coloured hairspray into it and it set solid, I haven't washed it for 10 years."
Beauty experts have been known to recommend washing hair less to make it look better.
But leaving it for 10 years is very rare, just like a good cheese.
