Chris Pratt & Will Arnett Hilariously Narrate A Makeup Tutorial

Thanks to Allure ... Chris Pratt and Will Arnett were exposed to what we can only guess was their first makeup tutorial.

The Lego Movie actors added their own voices to the tutorial by narrating the whole thing. Hilarious! Wait till she breaks out the eyelash curler... Pratt and Arnett have no idea what it is!
