Jennifer Aniston

Now in her 40s, Aniston is enjoying the kind of success most actresses her age only dream about. Thanks to mid-budget comedies like "Horrible Bosses" and "We're the Millers," Aniston is earning millions on the backend of some very profitable movies. Aniston still earns money from endless reruns of "Friends" and she's an in-demand spokesperson. Aniston shills for brands like Aveeno and Vitamin Water.
