Dana Delany
Dana Delany is mostly known for her role on Desperate Housewives. Despite her career revolving around being a house, she has never been one! In fact, she's said many times that she doesn't want to be married. "I do like relationships, but I have to admit, the older I get, the more I love my solitude. I don't want to give that up."
Eva Mendes
Eva Mandes is famously in a relationship with Ryan Gosling, with whom she shares kids. Oddly enough, the two aren't interested in getting married. They've been together since 2011. "I'm not like anti-marriage or the institution, like other people. I love the idea of a union but I think it's a very old-fashioned, archaic kind of thing."
