According to the news on the 7th October from the Hong Kong media, Barbie had her 33rd birthday the day before but still needed to be in Hong Kong to work on her new movie with Nicholas Tse. At the time she was on a motor cycle with Nicholas, wearing a sexy black top which revealed most of her back and also her black bra. Seeing this, Nicholas ignores and did not have any particular reaction. Also at the time where the scene was taken, Cecilia did not come to visit Nicholas. The day before, Barbie rushed to Hong Kong to film her latest movie "热辣辣" (Hot Summers Day) with Nicholas. Although, it was Barbie's birthday on 6th October, she still had a very busy day working. Around 4pm that day, both Nicholas and her, had to go to Gough St, Central for filming, and at the time Barbie was wearing a black T-shirt that revealed most of her back and at the same time revealed her black coloured bra. This attracted many people that walked by and many stopped by to take picture. For that scene, Barbie had to ride a motor bike and from the top of the stairs, she whistled to Nicholas for him to come over. Then after she begs Nicholas to come in a flirty tone but then Nicholas did not have any particular reaction. Then she decides to throw a helmet towards him, seeing this, Nicholas rushes forward to catch it and then goes up the stairs to meet up with Barbie. Due to the fact many people stop by to take photos, it affected the process of the filming, making Nicholas having to run up and down the stairs five to six times, before the director was okay with the shot. After the filming, Nicholas accepted interviews from the media, when they asked whether his wife, Cecilia, would come to visit, he shakes his head indicating that she won't. As for Barbie, she went to a close by gallery for a rest as it was air conditioned. However, when the media approached Barbie for an interview, the staffs stopped them, and soon Barbie left in a car. Within about an hour, they got changed into another set of clothes and continued filming. Sources: 022.net
