Celebrity Jennifer Aniston on Kim Kardashian's Butt Pic: I Did It First The Horrible Bosses 2 actress jokes that she pioneered the butt-baring magazine cover photo By Kathy Ehrich Dowd and Phil Boucher Phil Boucher Phil Boucher is an editor at PEOPLE and based in London.

Not quite – but the 45-year-old actress points out that she did pioneer the derriere-baring magazine cover photo way before breaking the Internet was even a thing. “I was an original, all right?” Aniston joked to Extra at the Horrible Bosses 2 premiere Thursday in L.A. “Sorry, Kim K.” Aniston was referring to her 18-year-old Rolling Stone cover, which featured the Friends star lying face-down on a bed, sans clothes, with her bare bottom visible in the background. “That was just innocent,” she said in a sly comparison to Kardashian’s controversial Paper magazine shoot. “There’s nothing aggressive about that.” Aniston might have laughed off that long-ago cover, but the Cake star admitted she recently had a “mortifying moment” when fiancé Justin Theroux discovered her role in the cheesy comedic horror film Leprechaun. “He was flipping through the channels and he stumbled on that,” Jennifer said on The Graham Norton Show in the U.K on Friday. “And that was our next two hours, much to my embarrassment.” Aniston also playfully addressed her iconic Rachel haircut, admitting it was a lot easier to manage when longtime stylist Chris McMillan styled it for her. “My hairdresser was loaded when he gave me the haircut,” she joked. “He had a great time with the blow-dryer, but I didn’t think that I would have to do it myself.” “He then leaves me with a round brush and hair dryer. I didn’t know what I was doing,” she continued. “I only had that style for a season and then it was gone – that baby had some legs!” Want more stories like this?
