Gary Barlow has ruled out taking on theatre roles because he doesn't think he's ''good'' enough.

The Take That frontman may have his own talent show, BBC's 'Let It Shine', which has the aim to cast five guys to play the boy band in a new musical and he may have co-written musical comedy 'The Girls' with childhood friend Tim Firth, but he won't be acting on stage anytime soon because it's too tough.

He told the Metro newspaper: ''I'm not good at that, I swear. Look at our cast, they do the show eight times a week! That is incredible.

''I have total respect, but it isn't for me, I'm too much of a diva. It's been completely by accident that I've got into theatre. I'm most at home on stage with Take That singing our songs. I met Tim when I was 15 and we've kept in touch. He went off to be a playwright, I went into music.''

'The Girls' is based on the 2003 film 'Calendar Girls', which is a true story about a group of women who made a nude calendar for charity and was previewed in front of a star-studded audience at the capital's Phoenix Theatre on Monday evening (20.02.17).

And the 'Giants' hitmaker previously said he was feeling ''nervous'' about the opening of the show.

Replying to a fan who told him she'd bought tickets for opening night, he tweeted: ''Nervous already xxx (sic)''

The 'Back For Good' singer is grateful to all his fans who have purchased tickets for the production's West End run.

He tweeted: ''Thank you to everyone who's booked tickets to see @thegirlsmusical and no booking fees ! #hurahhhh (sic)''
