Justin Timberlake and girlfriend Cameron Diaz are putting off marriage to prolong their sex life. Timberlake and his girlfriend have long been rumored to be engaged, but the singer believes a wedding will mean the end of the couple's bedroom activities.

The singer says, "That's the thing about marriage. We like having sex. Why would we want to ruin a good thing?"

Appearing on The Ellen DeGeneres Show last month, Timberlake denied an engagement before joking, "(Cameron) hasn't given me a ring. I've waited for her to get down on one knee and ask."
