Robbie Williams chills in his back garden wearing just a pair of Calvin Klein pants

He’s known for his upbeat and cheeky persona. 

And Robbie Williams looked happy and relaxed as he kicked back in the garden, wearing just a miniscule pair of Calvin Klein underpants on Tuesday.

Appearing on his wife Ayda Field’s Instagram Stories, the former Take That star, 48, smiled widely as she captioned the snaps: ‘Happy face.’ 

Ayda, 43, went on to upload another shot of her husband with an over expressive pout, which she captioned: ‘Sad face.’ 

Robbie looked incredibly chilled as he sat on his garden chair shirtless.

The Angels crooner showed off his impressive selection of tattoos, while layering several statement piece necklaces around his neck. 

Going without styling his platinum grey hair, Robbie looked relaxed and carefree for the social media snaps.

Robbie has been married to Ayda since 2010 and the couple have four children together; Theodora ‘Teddy’, nine, Charlton ‘Charlie’, seven, Colette ‘Coco’, three, and Beau, two.  

Making the most of his down time, Robbie’s schedule looks to be getting a lot busier in the near future as his new album XXV is coming out on September 9, while a biopic about his life is currently being filmed in Australia.  

The biopic, titled Better Man, will cover his incredible rise to fame from boy band heart-throb to stadium superstar.

Production has begun on the big budget film – billed as ‘a musical fantasy’ – which is being made in Melbourne by Australian filmmaker Michael Gracey who directed the box-office smash The Greatest Showman.

British actor Jonno Davies, 29, best known for the Amazon Prime series Hunters, will play Robbie as a younger man.

Other members of the cast include Australian actors Kate Mulvany (The Great Gatsby), Damon Herriman (Mr InBetween), and filmmaker-actor Anthony Hayes, whose feature film Gold is currently streaming on Stan. 

Robbie first rose to fame in the all boy band Take That, before launching a successful solo career in 1996, with a string of UK hit singles and albums following.

In 2006 Robbie made it into the Guinness Book of World Records after he sold 1.6million concert tickets in a single day.

The filmmakers have been careful to avoid comparisons to recent musical biopics like the Queen film Bohemian Rhapsody, and the Elton John story, Rocketman.

In an official statement, the production said the film was ‘a satirical musical based on the life of a pop star’.

The film will feature ‘re-imaginings’ of Robbie’s hit songs, and stunning visual effects in order to explore the ‘inner demons’ the super star has had to battle both on stage and off.

‘To tell Robbie William’s beautiful, distinct story, back home, in my own city, is a dream come true,’ Gracey said in a statement.

‘There is a creative energy that burns across the Melbourne film industry, and I know this movie will thrive here.’ 

He went on to describe Robbie as an ‘everyman’ who has an ‘incredibly relatable story’ about following your dreams.
