VIDEO : Kendall Jenner Can't Keep a Straight Face in New Estée Lauder Video...

Kendall Jenner might be taking a note from Cara Delevingne and her many funny faces. The star gets silly in front of the camera (again!) for her latest Estée Lauder promo video, which promotes the brand's new Pure Color Envy Liquid Lip Potion (a high-octane gloss with the full coverage of lipstick). This is the star's second big video release for Estée, following her dance-happy promo for the Courrèges collection back in March. Kendall stuns in the new ad (as per usual), sporting a vibrant red lip hue and vampy all-black ensemble.
