Ronaldo stars in weird face-fit commercial

Football superstar Cristiano Ronaldo has starred in a bizarre commercial for a device that is purportedly good for your face.

Ronaldo recently travelled to Japan to promote the product called Pao Facial Fitness. It requires the user to put the winged device in their mouth and bob up and down.The resulting flapping motion is supposed to strengthen their cheeks.Why Ronaldo chose to endorse the product is anyone's guess, but we can only assume it was for a huge sum of money. Massive money, in fact.After all, it's estimated that he made more than $80m in 2013 alone.Either that, or Ronaldo has been pranked in a big way.The Real Madrid and Portugal star also endorses another product for the Pao company, which is a massage device that closely resembles genitalia.For someone who is renowned for his exploits on a football pitch, this latest move appears a blatant own goal.
