Kim Kardashian, Jennifer Aniston has a message for you: She was the first to pose butt-naked for magazine covers.

The Horrible Bosses actress, who exposed her bottom on the cover of Rolling Stone magazine in 1996, compared herself to Kim Kardashian West, who just did a naked photoshoot for Paper magazine.

The Rachel Green actress is clearly nude in this portrait taken by renowned photographer Mark Seliger, but only a glimpse of her derrière is visible.

Aniston told Extra at her Horribe Bosses 2 launch on Thursday that her shoot was “way” ahead of Kim’s.

Jen said: “Oh, yeah. I was an original.

“[My picture] was just innocent, there’s nothing aggressive about that,” she remarked, possibly referring to Ms Kardashian’s daring full frontal nude photo in Paper Magazine.

“Sorry, Kim K,” Ms Aniston said.

“It’s confusing,” Madonna, 56, remarked. “Nipples are considered forbidden and provocative bit exposng your ass is not. #Flummoxed.”

Kim Kardashian’s nude bum cover has gotten a lot more attention than Jennifer Aniston’s Rolling Stones naked bum cover because of the size of her butts. Apart from her cleavage, Kim’s backside is the most talked-about feature of her body. The “Keeping Up With The Kardashian” star has been linked to plastic surgery for her butts, according to reports. In a series of photos, Kim is seen holding her black dress down to display her famed endowments, including her bottom and breasts. Kim has also gone frontal and displayed all in other photos for Paper magazine.

“We always run lines together. That’s one of the fun things that partners get to do. How could you not? It’s just so silly,” the actress told the publication.

Jen’s BFF Courteney Cox and her fiancé Johnny McDaid were photographed at the Hollywood premiere but Justin was MIA on the red carpet.
