Jeff Bridges admits he wouldn't cheat on his wife because he is ''so in love with her'' and he knows ''sex can lose you everything''.
Jeff Bridges would never get sexually involved with an actress.
The 60-year-old actor, who has been married to his wife Susan for 33 years, claims sex can ruin a person and he would never be tempted to cheat on his partner.
He said: "You don't want to get sexually involved with the other actor. It spells trouble. My family was and is too precious to me. I know sex can lose you everything."
Despite his lengthy union with Susan, Jeff - who won the Oscar for Best Actor for his role in 'Crazy Heart' on Sunday (07.03.10) - insists their passion hasn't waned over time and their relationship keeps getting better.
He said: "I'm so in love with her. The relationship just keeps getting better and more intimate and sexier and all that stuff. My wife supports me and it makes me love her even more."
However he admits he wasn't always such a good guy, and did enjoy a wild time when he was younger.
He said in an interview with The Sun newspaper: "It was harder earlier on. Getting married was frightening.
"No matter how much womanising you do as a single guy, you always think there's more to be done."
