Recently, Bosco Wong, Niki Chow, Joey Meng and Benjamin Yuen attended a promotional event for TVB series A Change of Heart. It was announced that this week's average rating so far is 30 points, peaking at 32 points. Earlier, Bosco and Niki had promised they would wear swimming briefs and a bikini if the ratings reached 32 points, but yesterday they didn't fulfill their promise, reports The Sun and Mingpao.All Bosco did was take off his black jacket, and put the bikini top over his black tank, while Niki placed a bikini bottom over her outft over herself. Benjamin Yuen also joined them by wearing a bikini with a floral design over his top.Bosco explained that he just learned about the promotional event that afternoon: "It's just too rushed I didn't have time to prepare. I promised to wear one, then I will, but I have to lose some of the fat first. Next time at the celebration dinner, I wear it, it doesn't matter for guys." Niki complained, "Why is it only me and Bosco wearing it? I said if the ratings reach 35 points I would wear a one-piece swimsuit. I never said I would wear a bikini for 30 points." Asked whether if she will agree to wear a bikini if there is a celebration dinner for 35 points rating? Niki said: "35 points, I'll wear it with Mun Mun then!" Mun Mun replied:, "Sure, I'm going on vacation anyway, I can put up swimsuit photos for people to look at. (A bikini?) Of course, I have never had a one-piece swimsuit." Niki added she may not be in HK when the time comes, but will upload her two-piece swimsuit picture.
