Lewis Hamilton has come under fire for spraying a hostess in the face with champagne after winning the Chinese Grand Prix in Shanghai on Sunday. The reigning world champion won his second race in three to start the 2015 season, but his podium celebrations have drawn some criticism. A leading group which campaigns against sexism has condemned the behavior of the driver as 'selfish and inconsiderate', saying he should be forced to apologise for 'specially directing' the bubbly into the woman's face. Lewis Hamilton celebrates winning the Chinese Grand Prix by spraying a hostess in the face with champagne . The hostess looks less than impressed as she is sprayed with champagne on the podium in Shanghai . Roz Hardie, chief executive of Object, a campaign on media sexism and 'sex object culture', said: 'The photographs appear to show that the woman is not just being splashed, but that the champagne is being very specifically directed into her face, which does not look like a voluntary piece of horseplay on her part. 'If this if the case we think Lewis Hamilton should apologise for his actions and think carefully about how he behaves in the future. For most people, it would be apparent that she is not enjoying it. 'It is surely a very difficult position to be a grid girl and she would have had little option but to stand there and take it. That is something of which he should be aware. But instead, he appears to have abused her position. 'It's unfortunate that a great victory has been marred by what appears to be selfish and inconsiderate behaviour.' Hamilton's celebrations have led to criticism of the two-time world champion . Hamilton controlled the contest in Shanghai to seal his second victory in three races this season . Hardie added that the episode highlighted the more general issue of women being viewed as sexual objects in the motoring world. She said: 'Motor racing appears to unnecessarily portray women as sexualised objects and that probably makes it even harder for the women to stand up for themselves. We would hope people in the industry would be respectful to these women. On Twitter, Hamilton was described as a 'bully' and 'disgusting'. Another user simply said: 'Man please stop spraying Champagne on the Podium Ladies. They don't like it', while one outraged user said he was a 'scumbag - an embarrassment to UK'. Another wrote: 'Have a bit more respect for the ladies please. Spraying Champagne in her face was out of order #child #idiot.' Hamilton sprays a hostess after winning the Spanish Grand Prix in Catalunya last May . And one tweeted: 'Shame on you F1 and Lewis Hamilton for disgraceful treatment of women during champagne celebration#sexism.' It is not the first time the racing icon has whipped out his victory move. He celebrated in a similar fashion after winning Spanish Grand Prix last year, which was his fourth consecutive win in a row and the one that finally put him on top of the driver's standings. And although he lost the Austrian Grand Prix to teammate Nico Rosberg, he didn't shy away from popping the cork directly at a hostess. The 30-year-old was even asked to demonstrate his champagne skills on Graham Norton's talk show in 2013. But not everyone was offended by his behaviour. Many found his actions amusing, while another said: 'I can think of worse things to happen at work than getting sprayed in the face with champagne by @LewisHamilton.. Lighten up people!' Hamilton and his team-mate Nico Rosberg had a spat when the German said his team-mate slowed him down . Rosberg was unhappy as he felt that Hamilton backed him up into the reach of Sebastian Vettel .
