Jennifer Aniston, GQ
Twelve years after her first nearly nude magazine cover, Jennifer Aniston appeared on the January 2009 cover of GQ in nothing but a necktie. It wasn't the first time the star had graced a magazine cover in the buff — she appeared on the cover of Rolling Stone in 1996 at the height of the Friends mania — but it just might have been the best. At the time, the former television sweetheart was promoting the family-friendly tear jerker Marley & Me, which was released two days after the provocative cover hit newsstands. Critics speculated that GQ was selling Aniston as an "all-American woman" to complement the issue's patriotic theme, and audiences were happy to have her back on top. The then 39-year-old had never looked better. Take that, Brad.
