Kai is dressed like a tiger in the adorable snap

Wayne and Coleen Rooney‘s son Kai clearly dotes on his little brother Klay.

The family celebrated Klay‘s first birthday yesterday and Coleen, 28, uploaded a super-cute Twitter photo of four-year-old Kai making sure his sibling enjoyed himself.

Kai is dressed as a tiger in the snap and pulls a jokey growling face, presumably at little Klay.

‘My big boy Kai, entertaining klay on his birthday!! Tiger fun!!’ Coleen captioned the shot.

The Rooneys are currently holidaying in Portugal, where Wayne, 28, is preparing for the World Cup at the England training camp.

In Coleen‘s picture, Kai appears to be in a garden and is surrounded by pretty pink flowers and a fruit tree as the sun shines down on him.

The toddler had a busy day yesterday – he was also snapped supporting Wayne as he practised with his England teammates at the Algarve’s Vale Do Lobo resort.

It seems Wayne enjoyed having his son watch him play.

‘Good training session today with the England lads and Kai was there again cheering on the team,’ the Manchester United star later wrote on Facebook.
