Kim Kardashian had a very Kimsanity way of showing her support to her baby daddy, Kanye West, Friday night.

The reality star wore a cut-out little black dress that clearly left no room for undies, and showed it off via a selfie she took in a restroom at the American Airlines Arena  in Miami!

West was in the background of the pic, taken before he hit the stage with his The Yeezus Tour  last night.

"Bathroom selfie right before Yeezus hits the stage," Kardashian wrote  to her followers.
