Five days after beating Rosberg at the Chinese Grand Prix to extend his lead in the drivers' championship, Hamilton was the chief attraction at a routine pre-race news conference in which he was asked also about his champagne-spraying celebrations.
It was reported, earlier this week, that Hamilton had upset and embarrassed a podium ceremony hostess by squirting champagne into her face after winning last Sunday's race, but this was denied by her on Thursday before Hamilton commented.
"It lasted for only one or two seconds and I didn't think too much about it," she was quoted saying. "I think some foreign media are more sensitive about the topic than local media!"
She added: "I can't control other people's behaviour when I'm working. I hope the public doesn't make too much of it, or that it affects my personal life."

Hamilton said he had not been aware of the alleged controversy until he was told of it on arrival in Bahrain.
Asked about his contract negotiations and a particular suggestion that one reason why his new contract had not been agreed and signed was his request for number one status, he said he had never in his career asked for any kind of preferential treatment.
