The 34-year-old Coldplay singer - who has two kids with wife Gwyneth Paltrow - joked that his admiration for Gary Barlow, Robbie Williams, Mark Owen, Howard Donald and Jason Orange made him question his own sexuality.
Presenting Gary with a gong for his songwriting achievements at the Q Awards yesterday, Martin confessed that his favourite bands as a teenager were, 'U2' and 'five handsome, strapping men from Stoke and Manchester'.
'I'm not afraid to admit it, they made me ask the question 'Am I gay?',' he added.
Coldplay walked away with the Best Band In The World gong.
