Will Smith has named "good sex" as the secret ingredient to a happy and long-lasting marriage. Smith, who has been wed to Jada Pinkett Smith for nine years, is adamant being passionate in bed is the key to domestic bliss.

He says, "Really, really good sex. I'm really good at it. (Also) we talk a lot. Sometimes people hear us talking and think we over-talk situations but communication is everything."

Smith was previously married to Sheree Smith, who he divorced in 1995 after three years of marriage.
