Dermot O'Leary, the host of The X Factor, has shared the secrets behind his on-screen dancing, admitting he improvises without any rehearsal.
Speaking to Nick Grimshaw on BBC Radio 1, O'Leary confirmed his dancing will return when the show returns in 2016, but he has no plans in place. 'Sometimes you don't even know it's going to happen,' he said.
He recalled a moment when dancing girls appeared unexpectedly just before going on air. 'Then I go out and do a burk-y dad-dance and people on Twitter say "that was rubbish",' he added.
