London, Nov 4 : Lewis Hamilton celebrated becoming Formula One world champion - by partying until 9am and downing only two glasses of champagne.

The 23-year-old race ace and his pop star girlfriend Nicole Scherzinger, who was trackside to witness Hamilton's amazing victory in the Brazilian Grand Prix, were joined by his family and McLaren staff.

However, Hamilton insisted the only thing he was dizzy on was his pride at becoming the sport's youngest world champion.

"I only had a couple of glasses of champagne," the Mirror quoted Hamilton, as telling a press conference in Sao Paulo, Brazil.

"I remember sitting there towards the end of the night and a song came on, We Are The Champions by Queen.

"I saw all the team members - my mechanics, engineers, catering staff, the bosses, my dad - and everyone was so happy.

"I just sat there and took it all in. It was a feeling you can't put into words, to see how happy you have made everyone after all the hard work they have put in, and how satisfied they are. That was really my present last night, seeing all that," he added.
