What celebrities do you get confused with each other?

I just saw Dejavu and realized that Morgan Freeman and Denzel Washington are two seperate people. I don't know how I confused them, Morgan is even older I think. I also used to get Rene Zellweger and Reese Whitherspoon mixed up a lot. Do you get any famous people confused with each other?

(And don't give me Mary Kate and Ashley - ha ha I'm a step ahead of you!)
