Jennifer Aniston

Jennifer Aniston catapulted into stardom as spoiled-but-lovable Rachel Green on the hit TV series Friends. "The Rachel," her layered haircut, sparked a nationwide trend and transformed Aniston into a style icon.

In 2000, she married heartthrob Brad Pitt, but filed for divorce four and a half years later. When reports emerged of Pitt's romance with Mr. & Mrs. Smith costar Angelina Jolie, Aniston earned admiration from fans for her poise and resilience. But she quickly rebounded with her The Break-Up costar Vince Vaughn and younger heartthrob John Mayer until choosing to walk down the aisle again with Wanderlust costar Justin Theroux, who proposed in 2012.
