Jen Aniston looks almost unrecognizable in the new issue of Allure Magazine -- where she bashes one of her most famous looks.

Aniston, rocking a new hair 'do and a serious tan, sports a new look in the magazine's February issue -- where she tells the world she hated "The Rachel" haircut on "Friends."

"Let's just say there have been moments I'd rather not relive, like that whole Rachel thing," says Aniston, "I love Chris [McMillan, her stylist], and he's the bane of my existence at the same time because he started that damn Rachel, which was not my best look. How do I say this? I think it was the ugliest haircut I've ever seen."

She may not have liked the look, but she's still cool with Chris -- he still works with her now.
