LONDON: 'Yes Man' actress Zooey Deschanel says committing to one man is not ''necessary'' in today's society. Zooey Deschanel doesn't believe in marriage. The actress-and-singer refuses to commit to one relationship for the rest of her life and believes people should experience a variety of lovers. She said: "People don't have to get married anymore. We're a generation that has progressed in many ways, from the ones before us. I think that the idea of romantic love is about marriage is over. Now all love is romantic love. Getting married is not a necessity, and staying with one person is not a necessity." Although she doesn't believe in marriage, last year the 29-year-old beauty got engaged to Death Cab frontman Ben Gibbard after he popped the question. A source said: "They are thrilled. "Zooey was swept off her feet, and Ben is so excited."
