Wong Cho Lam (王祖藍) and his girlfriend, Leanne Li (李亞男), Roger Kwok (郭晉安), Akina Hong (康華) and others were preparing outdoor scenes for new series, Inbound Troubles 2 (老表，你好Hea！), in Causeway Bay (銅鑼灣).
The scene was about Cho Lam helping Leanne Li to ask her voters for support, reports Asian E-news Portal.
On the day of the shoot, Leanne wore a tight fit dress and was perspiring.
When asked about her feelings collaborating with her boyfriend, Leanne said: "I thought I would keep laughing but he was quite serious."
She also remarked that he did not give her any special treatment.
When asked if his girlfriend had potential to become a TV Queen, Cho Lam said:
"She has always been the best female lead in my heart.
"As for her performance, she knows how to use her strengths and weaknesses.
"She resembles a vase and is a vase in the series too. She is an 'extra' and I will make her become an 'extra'.".
