Aniston posed nude for the cover of Rolling Stone magazine in March 1996.
Speaking to Extra at the Hollywood premiere of “Horrible Bosses 2” Thursday, Aniston bragged that her bare derriere appeared “way” before Kardashian's, reports usmagazine.com.
“Oh, way, yeah. I was an original. (Mine) was just innocent, there's nothing aggressive about that,” the 45-year-old said.
“Sorry, Kim K,” she added.
Aniston's cheeky cover marked her first solo cover for the magazine. The actress had previously posed for the magazine with her four “Friends” co-stars in 1995.
