PIC: Jen Aniston Flashes Chest in Open PJ Top

 Michael Thompson for Allure

Jennifer Aniston's Friends-era haircut had plenty of fans — and its own nickname — but the actress was definitely not one of them.

"Let's just say there have been moments I'd rather not relive, like that whole Rachel thing," the Just Go With It star, 41, tells the February issue of Allure, in which she poses in an open pajama top. "I love Chris [McMillan, her hairstylist], 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. What I really want to know is, how did that thing have legs?"

Another thing that baffles Aniston? ABC's reality competition, The Bachelor.

"I was mesmerized by these girls, they meet this guy, they have three dates together or something, and they're weeping as though they've just lost the love of their life," she tells the mag. "I don't understand that."

Rather, the actress recalls the heyday of Friends and its fellow NBC juggernaut, ER.

"Look at Baby George," she says. "Baby Clooney. ER was right next door to us on the soundstage. That was really fun. I remember when we used to do crossovers like that. See, NBC used to be really cool. Then, you know…"

Not to say Aniston — who calls herself a great party planner and drink mixer, particularly when it comes to Bloody Marys — is in the habit of tooting her own horn.

"I'm actually comfortable in goofdom," she tells the issue. "Not taking myself seriously is one of my favorite things to do, because I don't. Ever."
