Jennifer Aniston, Brad Pitt Top Forbes' Famous Faces List

People can't get enough of Jennifer Aniston. Neither can Us Weekly, Star or other popular celebrity magazines.

Aniston sits atop's first-ever analysis of top-selling famous faces, based on several factors, including newsstand sales of celebrity weeklies People, Us Weekly, In Touch Weekly, Life & Style, OK! and Star over a six-month period ending June 30, as supplied by the Audit Bureau of Circulations.

The 38-year-old actress graced six covers — appearing on every magazine except In Touch Weekly at least once during the time period — with her face collectively selling more than 5 million copies, the Web site said Tuesday.

Aniston's ex-husband, Brad Pitt, takes second place on the list, followed by Scarlett Johansson, Angelina Jolie, Reese Witherspoon, Katie Holmes, Carrie Underwood, Jennifer Hudson, Valerie Bertinelli and Kelly Ripa.

Britney Spears isn't on the list even though the 25-year-old pop star snagged 18 single covers during the six-month period. Spears' face fails when it comes to sales, said, and she is only slightly more likable than Paris Hilton.

Consumers have grown tired of Spears' consistently bad behavior, In Touch Weekly Editor in Chief Richard Spencer is quoted as saying.

"Usually there's a roller coaster of emotions," he says. "But unfortunately for Britney, there's been no roller coaster lately — there's just been the downhill."

Also missing from the list: Lindsay Lohan and Jessica Simpson. calculated the tabloid appeal of a celebrity by comparing how many issues a cover sold with the magazine's average newsstand sales. The Web site then factored in the number of full covers a celeb graced, and ranked his or her consumer appeal using data from Encino, Calif-based polling firm E-Poll Market Research to rule out flukes.
