Robbie Williams’ wife has shared a hilarious photo of the singer reading Gary Barlow’s autobiography in the bath.

The snap shared on Ayda Williams’ Instagram account shows Robbie looking intent on Barlow’s book A Better Me while he lounges in the tub.

“The moment you catch your hubby @robbiewilliams in a tub with @officialgarybarlow #mcm #rubadubdub#threesacrowd Awxx,” said X Factor judge Ayda.

Barlow saw the funny side, also sharing the picture of his former Take That bandmate.

“Love this!” he said, adding a crying with laughter emoji.

Robbie left Take That in 1995 before briefly rejoining them to create the Progress album in 2010.
