According to Rolling Stone magazine, Miller believes that it isn’t realistic to think that monogamy is easy. The Casanova star feels that temptation is strong because humans have animal instincts.
Miller experienced those instincts first-hand when her boyfriend, actor Jude Law, cheated on her with his children’s nanny. Looking back on the situation now, Miller, 24, says, "Monogamy is a weird thing to me. The fact is, no one is perfect."
Miller added that she gets her free spirit thinking from her parents. The beauty added, "They were really liberal in the early years and I knew from the start my parents were naughty."
Miller will soon be seen in the film The Factory Girl, in which she plays Edie Sedgwick. Miller said of Law, 33, "Our relationship has been though very difficult times and there’s something inside me I don’t like about it now. There are thing that will never be the same."
