The Emperor Entertainment Group held its annual spring dinner at the J.W. Marriott hotel.

True to form, the company's guests and stars, for once without anything to promote, allowed themselves to behave more casually and joke around with each other. Both Twins, Gillian Chung Yan-tung and Charlene Choi Cheuk-yin, played up to recent rumours in the Chinese press by saying they had sent SMS love messages to their alleged boyfriends as a joke.

However, Joey Yung Cho-yee (pictured) proved to have the most guts when it comes to humour. After continually disrupting the dinner's lucky draw on Monday night, she had to be dragged off stage by a playful Jackie Chan. Then, in a half-kidding tone, Emperor boss Albert Yeung Sau-sing (pictured) asked if she had gone crazy. In response, the singer told her boss, whose temper is legendary, to stop nagging her. At that point, the venue reportedly fell silent - until Yeung himself started to laugh.
