Ada Choi and Max Zhang, who have been married for 13 years, have one of showbiz’s most-envied relationships. And apparently, the secret to their romance is how they both put each other and their kids before themselves.

Ada, 47, revealed on a variety show last week that she’s open to the idea of Max, who is also 47, marrying another woman should she die before him. She said, “I travel pretty often for work. Every time I take a plane, I tell him, ‘I’m boarding the flight now. Please look after our kids if something happens to me. It’s okay to get married again [if I die] as long as you find someone who treats our children well.”
