Graham Norton is appealing for the return of his childhood diary, which went missing during a gig in London.
The comedian was videoing the gig at The Roundhouse in north London in which he reads bits from the diary he wrote as a teenager.
He said, "I'm really upset about losing the diary. It has some really embarrassing things in it."
"I really want it back and would be so grateful if it was returned. I don't know why anyone would want to steal it," he added.
