The Sexiest Woman of All Time is...

"Men's Health" Magazine has named JENNIFER ANISTON the Sexiest Woman of All Time.

Aniston reveals to the magazine that the "least sexy" character she's played was Ferris Bueller's sister in the TV version of "Ferris Bueller's Day Off" . . . which aired from 1990 to 1991.

Jennifer also gives her own pick for the sexiest woman of all time.  She says, "It's a tie between Brigitte Bardot and Gloria Steinem.  But if I had to choose one, I'd say Gloria because, well, she's the full package.  That's sexy."

What makes a MAN sexy?  Jennifer says, "If he can make me laugh, has compassion, kindness, and an accurately sized ego."

ANGELINA JOLIE came in 10th place.
