Former "Beverly Hills, 90210" star Shannen Doherty told ET earlier this year that she chose to go on "Dancing with the Stars" for her father, but sadly her dad, John Thomas Doherty, died on Friday at age 66.
Shannen broke the news to People.com in a statement from her publicist, where the actress refers to her father as the "greatest man in the world . . . I love him with every inch of my being and cannot imagine life without him."
The actress, 39, recently became a published author, penning her memoir and self-help tome titled Badass.
