The razzmatazz of Formula One was in India for the first time, so it was only natural that celebrities were in attendance to add to the glamour quotient.From cricketing icon Sachin Tendulkar to tennis ace Sania Mirza to Bollywood megastar Shah Rukh Khan – they were all there in the paddock at the Buddh International Circuit, witnessing German Sebastian Vettel of Red Bull become the first winner on Indian soil.The F1-crazy Tendulkar, of course, had a special place, as he waved the chequered flag to signal the end of the race. He was accompanied by his wife Anjali and daughter Sara.Even before the start of the grand prix, Tendulkar could be seen conversing with F1 supremo Bernie Ecclestone, and interacting with the legendary Michael Schumacher with whom he has been friends for the better part of a decade.”What an experience it was to wave the chequered flag!!! Got to keep it as well!!! :-),” Tendulkar wrote on Twitter.An excited Sania tweeted: “A day at the races.. what fun:) Sebastian Vettel won, and it was superbly organised.. great day. Delhi it is.. all the force with Sahara Force India.. woohoo.. good luck.” Shah Rukh, dressed in a white shirt and sporting a small ponytail, was also among Ecclestone’s guests on the starting grid, as was fellow Bollywood actor Gulshan Grover. Rising star Imran Khan also watched the race, as did dusky beauty Chitrangada Singh.The graceful Deepika Padukone was seen together with Force India owner Vijay Mallya’s son Sidhartha, while Preity Zinta was busy taking pictures in the pit lane before the race.advertisementRepresenting foreign cinema was legendary British actor Rowan Atkinson, who was a special guest of the McLaren team.He was shown on TV feed giving his trademark exaggerated expressions when Ferrari’s Felipe Massa and McLaren’s Lewis Hamilton ran into each other.The cricket quotient at the circuit was enhanced by off-spinner Harbhajan Singh and opening batsman Virender Sehwag, who arrived in a Bentley and was almost mobbed by the security staff manning the circuit gates. In fact, the security supervisor had to shout at them to get them back to their job of checking vehicles!
