Yesterday Bosco Wong, Niki Chow, Michael Miu, Joey Meng, Vincent Wong and Elaine Yiu attended the promotional event for TVB new series A Change of Heart. Earlier Bosco suggested if the are high ratings, then he'll celebrate in a bathing suit with Michael and Niki, reports Mingpao.Unfortunately, Michael and Niki refused. Bosco said: "Michael and Niki aren't willing to wear one, tell Niki to wear a scuba diving suit then! Go to the beach and get so hot to death!" He expressed if nobody is going to accompany him, then if the ratings reaches 32 points, he'll fly solo and wear a triangle swim brief to celebrate. Michael said: "I look disgusting in a triangle swim brief. If I really have to wear one, then I will need to ask Nick Cheung for some tips on undergoing a 3 month physical training."Niki initially refused to wear a bikini, she joked she'll "rush away the viewers" if she does. However, Bosco complained she has to cherish her body, while Michael added if she doesn't wear a bikini at this age, she may not have the opportunity again. Under the peer pressure, Niki helplessly agreed to wear one if the rating reaches 35 points. She said: "I'm afraid I'll scare people, I'm only wearing a two-piece bathing suit." Niki disclosed because she's going to be filming for 3 months in, Mainland, she might be able to get away with her 'promise'!As the series premiere comes closer, Bosco is feeling more and more pressure. He expressed if the premiere gets 26 or 27 points, its already good enough because its hard to predict what the audience likes.Earlier Niki experienced a sudden flat tire incident on the highway while driving into Hengdian and almost got into an accident. She said: "I wasn't wearing a seat belt and I was fast asleep. The van ran up the curb and almost flipped. I really have to thank God." She frankly expressed she only accepted to shoot a costume drama in the summer because of the considerably good pay. Although she is not getting paid as much as Raymond Lam's 10 million RMB, but her salary is still enough to buy a home.
