LOL, Carina Lau implicated in Edison Chen sex scandal too?

I just picked up news that Carina Lau, Christy Chung (that Marie France woman?) or Cherrie Chung may be involved in Edison Chen sex scandal! LOL, Edison probably screwed every single Hongkong celebrities! Who can beat his record!

Anyway, while surfing around, I found this old clip on Youtube video of Carina Lau slapping Edison Chen in a movie and some kissing scene as well. Edison Chen said he knew Carina Lau since he was 15 years old and respected Carina Lau a lot. So, nay...this could just be another Hongkong celebrity gossips. But the shadowy photos of two women were released by the Hongkong Police.
