Fans of The Repair Shop were stunned by Will Kirk's 'real age' as he celebrated a milestone birthday. 

The antiques expert has featured on the BBC show since 2017 and has restored a range of different heirlooms and furniture. 

Will took to social media earlier this month and uploaded a photograph of him celebrating his birthday with a glass of wine. 

The post revealed his age, which many fans were surprised about, alongside another image of him as a child.

He penned, 'Here's to 40!' followed by a balloon, celebratory and cake emojis.

Will's post received over 12,000 likes and hundreds of comments from well wishers. 

However, some fans were shocked by Will's age and felt he looked younger.

One person commented: '40?!!! I thought you were about 28! Happy Birthday.'

Another said: 'Happy Birthday Will. Certainly do not look 40 !!'

'40?! Surely not. Happy Birthday sir,' someone else penned.

One fan gushed: 'Happy birthday Will you deserve it, you only look about 30 lovely photos.'

'Happy birthday! No idea you were 40 what! Xx,' another added.

Last year, Will announced the birth of his second child with wife Polly Snowdon.

The craftsman took to his Instagram in October and revealed Polly had given birth to a baby boy.

Will shared an adorable photo of the newborn's feet along with another snap of him carrying the baby out of the hospital. 

Alongside the post, he wrote: 'Three become four. I'm very proud of my lovely wife for the last 9 months. 

'Mum and baby doing well, including an incredibly excited big sister'.
