Ayda Field has shared an Instagram post dedicated to her "man crush", husband Robbie Williams, accompanied by a rather risqué picture of the object of her affections.

In the snap, Williams can be seen facing away from the camera as he looks out from a balcony with his right hand pointing up in the air and while he wears a vest in the photo, his trousers appear to have been pulled down to his ankles.

Field was clearly appreciative of the bare-bottomed photo as she captioned her post: "@robbiewilliams Everything Changes But You #mancrusheveryday #cheekyboy #rearoftheyear1997 #takethat AWxx."

She also set the picture to music by playing Take That's Everything Changes over the top of it.

According to the official Rear of the Year website, Williams picked up the award in 1999 while his former bandmate Gary Barlow took the title in 1997.

Field and Williams are celebrating their 10th wedding anniversary this year on 7 August. In that time, they've had four children together.

They welcomed the newest addition to their family earlier this year when baby son Beau was born to a surrogate.

The couple used the same surrogate surrogate for their second youngest daughter Colette, who was born in 2018.

Meanwhile, they also share daughter Teddy, seven, and five-year-old son Charlie.

The pair began dating in 2006, not long before Williams' 2007 stay in rehab. The star has candidly discussed his past issues with drink and drugs but has recently revealed the affects it had on his memory.
