Movie beauty Keira Knightley prefers men from her native Britain over those from America, because they are less vain. The PIRATES OF THE CARIBBEAN star is dating British actor Rupert Friend. She says, "UK guys don't take as much stock in their appearance. "Ask an American guy what his beauty regime is, and he'll tell you. Ask a Brit, and he'll say, 'Er... Guinness?' I like that."
