Prince William lets loose his 'fanboy' persona at FA Cup Final

Prince William has showcased himself as an authentic football fan, says an expert.

The Prince of Wales, who attended the FA Cup final this evening, showed what football is truly about.

Body language expert Judi James tells The Mirror: "William's body language at the Cup Final pretty much defined what football is all about for any authentic fan. He walked out on pitch wearing an expression of frowning, intense and formal-looking seriousness, showing a respectful approach to the occasion."

Ms James continued: "As he brought one arm up in a partial barrier ritual his eye-gaze was pointing downward while his mouth was pulled into an expression that appeared glum.

"Meeting the players though, William's true feelings broke through, though and he revealed his more excited, fan-boy side. William leaned into each shake but revealed which players he knew well via the use of a double hand clasp in the shake or even an acknowledging, knowing grin as he exchanged a few words of good luck,” she noted.
