Marriage advice- Kevin Bacon

Last night I was watching the "Road to the Red Carpet" on E! and Kevin Bacon and his wife Kyra Sedwick stopped by and talked with Gulianna. They were talking about her dress etc., and then Gulianna asked them how they made their 20 year marriage work in Hollywood. Kevin simply answered " Keep the fights clean and the sex dirty!!" I thought that was hilarious but so true. Maybe that really is the key to a happy marriage!
