Kissing co-star Eric Tsang was "very disgusting", jokes Hong Kong comedian Sandra Ng.Referring to their makeout session in the new movie Princess & Seven Kungfu Masters, Ng tells Life! with a laugh that she had in fact been "cheated" into having to do the scene at all.Speaking over the telephone from Hong Kong to The Straits Times Life!, the 47-year-old says in Mandarin: "I was telling director Wong Jing that he should add a few more funny scenes between Eric and I, so he threw in this storyline of Eric's character being secretly in love with me, and that we have to kiss."I haven't done a kissing scene in so long, and who knew that Eric would be so enthusiastic? His mouth completely covered mine. It was all very disgusting, and I was very unhappy about it. I feel so cheated by the director."In between hearty laughs, she adds of her pudgy co-star, 59: "Did he think he was Andy Lau or something? Even his tongue came out in full force."Princess & Seven Kungfu Masters opens in cinemas Thursday.
