The Take That frontman - who has co-written the musical comedy with Tim Firth, and though previews don't start in London until January 2017, he's already getting worried about the response to the show when it moves to the capital.

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)"

'The Girls' is based on the play and film 'Calendar Girls', which was based on a true story about a group of women who made a nude calendar for charity.

Meanwhile, Gary is also busy with his upcoming TV talent show 'Let It Shine' and it was recently announced Martin Kemp, Dannii Minogue and Amber Riley have signed up to join him on the judging panel.

Of the panel, Gary said: "Dannii, Martin and Amber all bring so much to this panel with the breadth of experience in music, acting, stage and TV. I can't wait to get started - it's going to be epic!"

Dannii - who was a judge on rival show 'The X Factor UK' until 2010 - is thrilled to be joining the panel and thinks the new format will give performers all the experience they need to "shine".

She said: "I'm so excited to be returning to the UK and joining the judging panel of 'Let It Shine'.

"To be a performer, you must have a burning desire to perform, then you train at all the skills you need to shine. This show gives everyone that chance. I can't wait."

The trio join previously-announced hosts Graham Norton and Mel Giedroyc.

'Let It Shine' aims to recreate the magic Take That had when it was originally comprised of Gary, Robbie Williams, Howard Donald, Mark Owen and Jason Orange.
