Many fans fell for the New Zealand captain for his classy reaction to their World Cup final defeat by England.
And now Sri Lankan supporters have made him a cake to celebrate his 29th birthday.
The Black Caps are currently in Sri Lanka preparing for next week’s first Test.
During a drinks break in the three-day tour match against a Sri Lanka Board President’s XI in Katunayake, Sri Lankan fans got Williamson’s attention in the crowd.
He enjoyed a bite of cake on the boundary before feeding a fan his own slice.
The birthday boy was spoiled with treats – team-mate BJ Watling presented him with another cake in the dressing room at the end of play.
