Justin Timberlake and girlfriend Cameron Diaz are putting off marriage to prolong their sex life.
Timberlake and his Charlie's Angels girlfriend have long been rumoured to be engaged, but the singer believes wedding will mean the end of the couple's bedroom activities.
The former N' Sync member 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."
