FWIW, the Wikipedia entry for Barbara Walters gives lots of information about her love life.
Walters has been married four times, to three different men. (How is this possible? She married Merv Adelson, her third husband, then divorced him, then remarried him, then re-divorced him.)
In her autobiography, Audition, Barbara Walters mentions an affairs that she had with Edward Brooke, then a married US Senator from Massachusetts in the 1970’s.
Walters has also been romantically linked with U. S. Senator John Warner in the 1990’s.
In 2007 she dated Pulitzer Prize-winning gerontologist Robert Neil Butler. Walters was only 78 at the time.
In conclusion, Barbara Walters seems to have enjoyed a rich and rewarding love life. No stability, but hey, girls just wanna have fun.
And I for once I agree with the famous quote from A. M. Rosenthal about journalist ethics and sleeping with your sources.
