But in a new clip from the season 11 premiere of Keeping Up With the Kardashians that airs Sunday, the 31-year-old reveals she was having second thoughts about the risqué photo shoot.
In the sneak peek video, Khloe tells Kim about a recent conversation she had with someone who brought up her past weight issues.
"Someone said to me the other day, 'I looked at old pictures of you' and they were like, 'You were so big.'" Khloe explains. "I was like, 'Why are you looking at old pictures of me?'"
"Guys and girls say this to me," she continues. "It's like a known thing how fat
That's when Kim suggests an idea to help Khloe get over the constant body image struggles she's faced.
"If you just do so many photo shoots, it will replace all the bad ones," Kim advises. Fans then learn that it was actually Kim who helped Khloe land the shoot.
"They want you to do the cover of Complex," Kim says, surprising Khloe. "I got you the cover of Complex, don't turn this down."
Despite the excited look on her face, Khloe gets hesitant when she thinks about actually having to pose for the photos. "Those people have the best bodies, I can't do that." In her solo interview, Khloe opens up even more saying, "I am not like you, Kim. I'm not as comfortable baring my naked ass on a cover of a magazine."
Well, we certainly know she was happy with the results. "Seriously I can't believe this shoot I did for @complex," she wrote on Instagram following her cover reveal. "I'm still blown away by how talented @stevengomillion is!!! Shout out to my glam team @1maryphillips and@cesar4styles. @monicarosestyle you always know how to make me feel so comfortable on set!! You are my security blanket!! I love you all madly!"

and moments leading up to Caitlyn Jenner's big night at the ESPY awards
