The `Hitch` actress - who has been dating Peruvian filmmaker George Augusto for nearly a decade - has an aversion to tying the knot because she thinks the institution is "archaic" and not a romantic thing to do. She told US TV talk show host Chelsea Handler: "It`s not personal. There are all these wedding shows and it`s so over-the-top, it`s so not about what it should be about. "I`m not like anti-marriage or the institution for other people. I love the idea of a union, that`s very beautiful. I just don`t think it should be a piece of paper because society tells me to. "It`s a very old fashioned archaic kind of thing. We did it for land originally, how unromantic is that?" The 37-year-old beauty admitted seeing older, unmarried people in love and referring to their partners can be "really sexy". She added: "I actually think it`s really sexy to be with someone in their 50s or 60s and be like `that`s my boyfriend`. But I think husband and wife are very unsexy words."
