Cristiano Ronaldo pokes fun at ex-Real Madrid teammate - then instantly regrets it when he spots a TV camera

The Real Madrid star's face says it all when he notices the camera and realises everything has been recorded

Cristiano Ronaldo is known for being a bit of a character.
He's often poking fun at his teammates on the training ground and apparently at his former teammates too, as the above video shows.
The clip captures the Real Madrid star in the tunnel ahead of their recent La Liga game with Espanyol, which they won 2-0.
He spots former Los Blancos shot-stopper Diego Lopez - who now stands between the sticks for the Calatan side - and goes to say hello.

Now it's not clear exactly what the Portuguese says, but according to a number of reports from Spain, the forward decides to crack a little joke... at Lopez's hairline.
"Wow, Diego, you've had like 3600 hairs put in," is what he apparently says to the keeper, before giggling with him and pulling him in for a hug.

But it's the cameraman who has the last laugh.
Pleased with his joke, CR7 goes to smirk and then spots the lens glaring at him.
His reaction is brilliant and he appears to instantly regret what he has just said as he holds his face in his hands.
Oh, Ronnie!
