American Men's Perfect Mate: Jessica Alba
The 24-year-old Fantastic Four star was followed by No. 2-ranked Sienna Miller and third-ranked Angelina Jolie.
New mom Britney Spears, who usually heads the 99-woman list, was a no-show this year.
The rest of the Top 10, in order: Brazilian model Adriana Lima (No. 1 last year), Access Hollywood correspondent Maria Menounos, Charlize Theron, Jessica Biel, singer Amerie, Natalie Portman and Eva Longoria.
James Bassil, editor-in-chief of AskMen.com, tells the Associated Press that the rankings were determined by 2.5 million readers and by the site's staff.
"We encouraged readers not to go on looks alone," Bassil says. "I don't believe it's an entirely accurate reflection of what a reader strives for in their long-term relationships, but at the same time, it's not a sheerly surface appreciation."
