The person attached to said bottom is Blac Chyna, and she just so happened to be working out in the same bedroom(?) as Kim Kardashian. SELFIE ALERT!

According to New York Daily News, Blac is - and this may come as a shock - "a model and former stripper, and is engaged to rapper Tyga. Like Kardashian, she also has a little one at home, named King Cairo Stevenson." Consider yourselves enlightened.

Kim posted these photos to Instagram with the caption 'Getting right for the New Year'. We're assuming she's banging on about her abs 'cause she sure isn't getting framing of any of the photos 'right,' lopping off heads and what not. Although, maybe she's got it spot on.
