What extra-marital affair? Sources close to George Lam and Sally Yeh say the Hong Kong celebrity couple have an open marriage.

"It's a mutual agreement between them," offers an insider. "They're still legally married. But he has his life and she has her life. That's how they see marriage."

In fact, Sally once broadcast that the secret to her 14 years of good relationship with George was to sleep on separate beds, sometimes.

"He and I have two different bedrooms in the house," the Cantopop queen once dished out to sina.com. "Yes, we do sleep separately, sometimes. It's better that way, especially for an old married couple like us."

It has been reported that George is currently seeing a forty-something old friend, while Sally is getting some 'quality' time with her badminton coach, Mike.
