Cameron and Justin like to keep things quiet

Cameron Diaz has vowed to fiercely protect her and boyfriend Justin Timberlake's privacy from the prying eyes of the press. The couple are followed everywhere by curious photographers and constantly grilled on their future plans by inquisitive reporters - but Diaz insists they will never let the outside world into their relationship. She says, "Justin and I have to keep it all to ourselves, private stuff, or we'd go insane." "Neither Justin nor I can help who we fall in love with - no one can." [Teen Hollywood]
