Jennifer Aniston Returns to Red Carpet With Justin Theroux and Her Favorite Look: Hairstyles Now and Then [Photos]

Jennifer Aniston hit the red carpet with fiancé Justin Theroux for yesterday's New York City premiere of HBO's Leftovers.

Theroux told US Weekly that he "felt great" having his beau at the event to support him--plus Aniston was looking great, wearing her long beachy-waves hairstyle.

This loose hairstyle, similar to the one she wore in the 2004 film Along Came Polly, is her favorite, reported Women's Wear Daily last month.

"It existed?" Said Aniston jokingly about the 'Rachel Cut' that will forever be linked to her Friends character.

It's been more than six months since Aniston shined in the spotlight at the Toronto Film Festival, which is an eternity for Hollywood's calendar. At the festival, she wore her hair smooth and straight.

But for her upcoming film Cake, she's been embodying a new look. According to People, her hair is darker and unstyled, which complements her character's baggy pants.

From the 'Rachel' to this recent unglamorous hairdo, Jennifer Aniston will remain a showstopper. Check out her other hairstyles.
