Cristiano Ronaldo has put his face to a bizarre new advertisement for Japanese television.

The Ballon d'Or winner has been in the Far East to promote a product called Pao Facial Fitness that claims to tone your face.

A YouTube video for the bizarre contraption has now reached almost 250,000 views.

The winged instrument goes in one's mouth and the user bounces their head up and down.

Tellingly, Ronaldo is the only person on the video not to put the device in his mouth.

Quite how much the Real Madrid superstar got paid for this we don't know.

Let's hope it's all an elaborate practical joke...
