Comedy queen Sandra Ng Kwan-yu took lessons from Mongkok prostitutes to perfect her massage techniques for her new movie Golden Chicken. But the fortissimo moaning, which has kept audiences in stitches, was all her own. 'That comes from everyday experience,' she told Singapore's Life magazine, adding she could identify with her role as a Hong Kong prostitute because her character was 'quite like me'. 'Let's face it,' added Ng (left). 'I couldn't carry off the role of a virgin, could I?' We guess not. Ng, now 37 and a veteran of 98 movies, hit the headlines a while back for revealing details about her long relationship with crooner Alex To Tak-wai. She will probably be more reserved about her current partner, at least until Golden Chicken goes to DVD. She's dating the producer, Peter Chan Ho-sun.
