If you didn't get this one correct, there is no use going further, because Jennifer Aniston is arguably the most popular of the Jennifer-s in Hollywood.

Known lovingly as Rachel Green (from the hit Sitcom series, FRIENDS), she even has a haircut dedicated to her! Yes, this just means you can go a salon and actually ask for a Rachel/Jennifer Aniston haircut.

And here's some trivia about Jen Aniston. Did you know she was actually called to audition for the role of Monica Geller? But she insisted that she could give a better performance with the role of Rachel Green. And what a performance it was!

With an Emmy for excellence in a comic role, she is also one of the highest paid TV personalities. (Imagine earning 1 million dollars per episode for the last two seasons of FRIENDS!!!)

We all know about her fairytale wedding to Brad Pitt and then the sad divorce! (Bad boy, Brad!) After that she has been linked to her The Breakup co-star Vince Vaughn after which they announced their "break up" in 2006.

Best Friend Status: Well, if you ever had a doubt about whether a colleague can be a friend, our Jen puts that debate to rest! On the sets of FRIENDS, she became friends with on-screen best friend, Monica Geller (Courtney Cox-Arquette) and as time passed, the reel best friends became real best friends.

What's best? Jen is the godmother of Courtney's daughter, Coco Riley Arquette. Now THAT'S friendship!
