She posted a picture of her note to him, which read: ''Boozy, On this very special day, I want to give you the gift of the things you love the most (besides us of course).

''Please spend your day watching and playing as much football as you like, eating as much chocolate as your heart desires, with all the time in the world you want. Scratch your balls. trump to your merry delight and be in boy heaven.

''Happy Birthday to the love of my life, your proud wifey (sic).''

And Ayda, 37, who has children Teddy, four and Charlton, two, with Robbie, captioned the post: ''Happy Birthday to my beautiful hubby @robbiewilliams !! May you have the best day today and may this year be the best year yet!! I love you boozy!!! #birthdayboy #mcm #robbiewilliams #silverfox #chocolateworld #cake #caloriesdontcountonyourbirthday (sic).''

Ayda also shared a picture of the balloons she bought for Robbie, with the words ''old as f**k'' written on them.

She captioned the image: ''let the celebrations begin #happybirthday #balloons #partytime #robbiewilliams #oldasfuck (sic).''

Robbie previously admitted he never had any plans to settle down but changed his mind once he met Ayda.

He said: ''I made a vow to myself that marriage and kids just wasn't going to happen.

''I looked at others around me and it seemed like a pain in the a**e. It looked tiring and awful and I didn't want that for myself. Yet here I am: married, two kids, feeling better about my life than I ever could have imagined.''
