Naomi Watts is one of Hollywood’s leading ladies, not to mention quite attractive. That makes it difficult to believe she’s never taken a walk down the aisle, especially because she’s had two major relationships with high-profile Hollywood actors such as the late Heath Ledger, and star of Ray Donovan, Liev Shreiber. Naomi and Liev were together for 11 years before calling it quits, so she may as well be married considering there are countless examples of people that have gotten married but not been together nearly as long. Apparently the two were engaged for a short time, but even still made it publicly known that they had no plans to tie the knot.
