They married in 2008 and have three adorable children Kai, seven, Klay, three and Kit, who is eleven months.
Celebrating Kai's seventh birthday Coleen uploaded an adorable picture of two of their sons, Kai and Klay, and wrote: "Our big boy is 7 today!!! Happy Birthday Kai, we love you xx"
We were focused on how cute Kai looks but fans couldn't help but notice that the birthday sign was spelt wrong and it didn't take long for people to point out the silly mistake.
One person wrote: "Happy birthday!!! (P.s the 't' and the 'h' are the wrong way round)
Others joked:
"Did Wayne write the "Happy Birthday"?"
"Lol who spelt that wrong"
"You've spelt birthday wrong pal!"
"No spellcheck?"
But Coleen was quick to reply to her comments and tweeted: "Thank you all for your lovely birthday wishes for Kai! Hahaha I know the sign was spelt wrong… it was dropped and quickly put back together."
Wayne revealed to the MailOnline that Kai might be taking after his dad when it comes to a football career: "If he does, that's up to him.
"Certainly every day he's obsessed by football, and every day he asked if I think he's good enough, so I'm sure he'll have a go and see if he can."
We can't wait to see Kai's skills on the pitch, but at the same time, if he wants to be a ballet dancer instead, we hope dad won't stand in his way.
It seems the three boys all get on really well too, Wayne recently uploaded the sweetest picture with the caption: "Best mates".
They are SO cute!
