In the horror film Baby Blues, Hong Kong actor-singer Raymond Lam gets to work alongside his girlfriend, Karena Ng.
However, she is not one of the two actresses whom he gets intimate with onscreen.
Newcomer Janelle Sing, playing his wife, shares a bed scene with him, and he also locks lips with Kate Tsui, playing a temptress singer, in an underwater scene.
But if making the film was an awkward experience for the real-life couple, he is not letting on.
Lam, 33, consistently dodges questions about Ng, 20, in a recent telephone interview with Life! and other publications.
Speaking in Mandarin from Hong Kong, he says: "All along, we've dealt with things in a low-key manner, but some of your media colleagues have written their reports in a provocative way. So I've decided to no longer talk about my private life."
And if wedding bells were to ring for him one day, he would want to keep that under wraps as well. "Outside of work, my private life is for my family members and not to be shared with work colleagues. And that would be a family matter. I would just let nature take its course."
While he skirted questions about Ng, who plays his feisty sister-in-law in Baby Blues, he was happy to talk about his kissing scene with Tsui, 34.
