The rivalry between Spanish football giants Barcelona and Real Madrid has turned nasty, and the latest victim looks to be Cristiano Ronaldo's vanity.

Catalan TV station TV3 have been caught photoshopping Ronaldo's ripped torso in a bizarre example of the animosity between the La Liga rivals.

As you can see, the Real Madrid superstar's chiselled eight-pack seems to have disappeared, along with his bellybutton.

It didn't take long for Real Madrid's very own station RMTV to notice the alleged malfeasance and mock TV3's attempt to make Ronaldo, who just helped his country win its first international title at the European Championship last week, "look two months pregnant."
