Being Maria Sharapova isn't as easy as it looks. You may get the wrong impression of her. She has won two grand slam titles - the 2004 Wimbledon singles crown and the 2006 US Open - which in itself brings a fair degree of pressure and scrutiny, but it doesn't end there. You're as likely to see her face on a billboard as on a tennis court. Over recent years she has advertised watches, mobile phones, cameras and sports gear to name but a few products. A recent Forbes magazine article revealed that she was the most highly paid female athlete in the world, making a whopping US$1,357,144 a day from work outside of playing tennis, made up of million-dollar deals with Canon, Motorola and Tag Heuer to name but a few. Sharapova is a player and a brand. Since she won Wimbledon at the age of 17 the endorsements have been rolling in. But when asked if the Russian star preferred photo shoots more than playing at yesterday's official press conference for the Watsons Water Champions Challenge, which will take place at Victoria Park from today to Saturday, her answer was emphatic. 'I don't agree with that at all,' she said. 'I've won two [grand] slams already and I intend to win a lot more. I train very hard to get the best results possible. 'I can't stop the perceptions of people in the outside world. Their views are out of my control. I've been playing tennis since I was four years old. I'm working hard on my game and I can hardly say that for the modelling. 'My main focus is just to keep winning [grand] slams.' This did not mean that the 19-year-old was adverse to spending some money on a few of the accessories that she sometimes advertises. She was in Hong Kong after all, so it would be rude not to. 'My hotel is in the centre of Hong Kong and there are definitely a few places nearby that I would like to shop in,' she said. 'But I haven't bought anything yet. I may do later in the week.' It's to be expected that with Sharapova's looks and talent she is a PR person's dream. Tennis, however, is why she is in Hong Kong as it is a major part of her build-up for the Australian Open. 'The tournament in Hong Kong is the only one I will play before playing in Melbourne so it is an important event for me,' she said. 'You only have to see the quality of the line-up playing here to know that it will be a tough competition.' All eight players attended the press conference, and while world number two Sharapova was getting all the media attention, the tournament's other major drawcard, Kim Clijsters of Belgium, who is getting married to American basketball player Brian Lynch in July, was happy to take a back seat. 'I like playing it low key,' Clijsters, 23, said. 'This is going to be my last year and I will still be retiring as planned by the end of it. I'm not the type of person to make my mind up about something and then change it. But because this will be my last year I've probably trained harder than I ever have before, so I'm hoping to go out on a high.' But you can't have a superstar around without having a superstar awkward moment. This came when a local reporter alluded to a rumoured romance Sharapova may be having with American player Andy Roddick. 'Oh my God,' the Russian said, while glancing aghast over at one of the tournament organisers. 'I think we'll finish on that!' Sometimes it's hard being the 'It Girl' of tennis.
