Kim Kardashian Makes a Surprise Appearance at a Makeup Class

Makeup artist Mario Dedivanovic was scheduled to give a makeup seminar to his Master class on Sunday and when his model canceled at the last minute, he called in a replacement, which just so happened to be Kim Kardashian.

Mario has been doing Kim's makeup for seven years and when she heard that his model canceled, she jumped on a redeye and flew to NYC to be his model for the seminar.

Here's Mario telling the class about the very special surprise:

It's kinda cute, Kim kinda looks a little shy about sitting up there in front of the class.

After she got all glammed-up, Kim took time to pose for a whole bunch of photos with the students.

We think it was super cool for Kim to fly across the country at the last minute to help out a friend in need...and we bet that is one seminar those students will NEVER forget!
