Sandra Ng Attends Boyfriend Peter Chan's 60th Birthday Party In See-Through Top; Steals The Spotlight

Recently, Hong Kong actress Sandra Ng took to her Instagram to share snippets of the birthday party she had planned for her partner Hongkong director Peter Chan, 60. 

And can we just say that it was probably one of the most star-studded parties we've seen in a while?

Louis Koo, Carina Lau, Sammi Cheng, Donnie Yen and Simon Yam were all present to celebrate Peter's big day, as was retired screen goddess Chingmy Yau, her husband and three daughters, Shum Yuet, Shum Yat, Shum Sen.

But even with all those superstars around, all eyes were still on the 57-year-old Sandra.

Making a grand entrance that she apparently rehearsed for, Sandra appeared in an electric blue blazer and a pair of black shorts.

She then took off her jacket to reveal a very sheer white blouse. So translucent it was that it basically looked like she wasn't wearing anything. 

No wonder Peter immediately hugged Sandra, seemingly worried that she'd expose herself. 

The actress eventually put her blue blazer back on after the party started.
