Jennifer Aniston has a guilty pleasure and it has nothing at all to do with fiance Justin Theroux. So what is it that the former Friends star feels guilty about enjoying?

Unless you’ve already gotten the inside scoop, there’s no way you’ll guess.

It seems Jennifer Aniston has a penchant for a certain reality show–and she watches it as often as she can.

She is an avid Keeping Up With the Kardashians fan. In fact, she’s recently been quite enthralled with Bruce Jenner’s transition to Caitlyn Jenner.

“I sadly am very much interested in the Kardashian-Jenner thing,” Jennifer Aniston confessed recently. “That’s a guilty pleasure for sure.”

So what is Aniston’s take on Caitlyn Jenner?

“I thought it was beautiful,” she said of the Vanity Fair cover that debuted Caitlyn Jenner following Bruce’s transition.

Can you imagine hanging out at Jennifer Aniston’s house–just kicking back and watching Keeping Up With the Kardashians on TV? Do you suppose that’s what she and Courteney Cox or Chelsea Handler–two of her closest female friends–do when they’re together?

Now admit it. If you hadn’t read this with your own eyes, would you have ever guessed that Jennifer Aniston’s guilty pleasure is watching the Kardashian family on TV?

Do you suppose Justin Theroux is guilty of this, too, or is this Jen’s thing alone?
