She just has to have all the attention!

Kendall Jenner hosted a launch party for Skyspace in downtown LA last night, and big sis Kim Kardashian took the opportunity to tag along and steal the spotlight in a see-through black dress. We guess it was National Nude Day! There isn't an inch of the reality star's body we haven't seen before, so we were actually not that shocked by her outfit choice.

Inside the bash, the mother-of-three cut loose and was seen dancing and singing along to husband Kanye West's "Famous" in a Snapchat video. It's laughable how little rhythm she has! She's married to one of the world's most famous rappers and has the body of a video vixen, but she can't dance to save her life!
