Despite Wayne's absence in the picture, followers were quick to comment that he must have taken the picture.
'Who took the pic', one fan questioned, while another added: 'Someone had to take the pic'.
Mail Online has contacted representatives for Coleen and Wayne for comment.
The snap is reportedly similar to one Coleen of her with Kai, 7, Klay, 4, and Kit, one, in bed - but has Wayne in it, according to The Sun.
The WAG affectionately captioned the snap: 'Happy 8th Birthday to Our Kai!!!
So proud of you and love you so much xx'The rest of the cute collage featured Wayne in a cute snap with Kai and middle son Klay, four, along with a fun photo of Kai with singer Ed Sheeran.
The star could not celebrate his birthday last Tuesday, as he had to travel to London by train with Everton for their Carabao Cup match with Chelsea.
The law requires him to carry out 100 hours of unpaid work and that meant a breakfast time wake-up call and a chauffeured trip in a £60,000 Audi to the community centre for another session of routine maintenance tasks which began at 9.39am.
