NICE, France - Formula One world champions past and present paid their respects to Jules Bianchi and mourned one of their own at the French driver's funeral on Tuesday.

Lewis Hamilton, the current champion for Mercedes, attended the service at Nice's Sainte-Reparate cathedral along with former champions Alain Prost, Jenson Button and Sebastian Vettel.

Bianchi, 25, died in a Nice hospital on Friday after suffering critical head injuries when he skidded off the track and hit a recovery tractor in last October's Japanese Grand Prix.
