The footballer can't wait to be reunited with his little family and has shared a picture of his son enjoying beach life in Barbados on Instagram.
The three-year-old had been buried in the sand in the Instagram picture, which Wayne posted alongside the caption: "Kai having a bit of fun on holiday, looking forward to seeing him!"
Meanwhile, Wayne is giving an 'American Idol' contestant with cystic fibrosis a VIP trip to watch him play for Manchester United
Wayne - who lost childhood friend Stephen Johnson to the disease last year - was so moved by the story of 16-year-old Kayden Stephenson on the US reality TV show that he got hold of him on Twitter.
Offering to fly Kayden and his family over from Oklahoma to watch him play a match against Real Madrid, he said: "Your story inspires me, reminds me of a friend I know.
"Thank you for being brave and sharing your story. No matter what happens on Idol, music inspires people and you inspire people.
"Keep doing it, you will help a lot of people."
Kayden then replied: "OMG! Dude. I can't believe you tweeted me. I'm glad I inspired you. I'm a soccer player and you inspire me."
