Warren Beatty slept with 13,000 women. How is that even possible?

[Updated 4.07 p.m] For all the hot Hollywood actors who are often said to be the biggest celebrity studs, you guys need to read a book.

The Dish Rag thinks Colin Farrell,  John Mayer, Jude Law and Gerard Butler should check the new biography, "Star: How Warren Beatty Seduced America." 

You guys are amateurs compared to Beatty.

The "Bonnie and Clyde" star's first  authorized bio details his career and his hyperactive love life with his leading ladies, emphasis on the plural. And "authorized" means he had to have okayed the author's estimate of his past lovers.
[Updated] Warren Beatty's attorney tells the Huffington Post that Biskind's book is not authorized.
"Mr. Biskind's tedious and boring book on Mr. Beatty was not authorized by Mr. Beatty and should not be published as an authorized biography," Bert Fields says. 
"It contains many false assertions and purportedly quotes Mr. Beatty as saying things he never said."

Author Peter Biskind's estimate of how many women succumbed to the legendary lothario's prowess?

 "12,775 women, give or take, a figure that does not include daytime quickies, drive-bys, casual gropings, stolen kisses and so on."
