Helena Bonham Carter
Despite famously being involved with Tim Burton for 13 years, Helena Bonham Carter has never been married. The two have children together and are still great friends, but marriage isn't even on the playing field "I don't plan on marrying or even dating. I feel very self-sufficient at the moment. I'm just going to work out who I am on my own and it's quite liberating."
Sheryl Crow
Sheryl Crow has had quite a dramatic love life. She used to be in an exclusive relationship with Lance Armstrong, one of the world's most popular cyclists. Right after the two broke up, Armstrong was caught up in the drama of his substance use that enhanced his cycling performance. Crow has been single ever since.
