I blame Kanye! Kim Kardashian has always posted several photos every day on average, but now that she's been using Kanye West for ratings, she's been posting bikini photos more frequently.
Kim rejected Kanye for a decade and now that they're an official couple, he's probably showering her with compliments, as if she needs any, and it's resulting in Kimmy posting more "No Photoshop" bikini pics on Twitter.
I can't think of anyone else as cocky as Kimberly Kardashian. Oh ya, Kanye! Hopefully they'll break up soon. I think they're feeding off of each other's egos.
