Reigning champion and 2011 title leader Sebastian Vettel has this week been holidaying with Bernie Ecclestone.
Bild newspaper published a photograph of the 24-year-old Red Bull driver waterskiing off the coast of Croatia, near F1 chief executive Ecclestone’s yacht ’Petara’.
The amateur photographer said: "I had no idea who I was photographing — I was just trying out a new lens."
Vettel will return to work on Monday, when he drives in Red Bull’s F1 simulator in Milton Keynes (UK).
