Of course, this wasn't just any regular day for Kendall and Gigi, the girls were on the set of their Vogue shoot, where Justin Bieber, Cody Simpson and Ansel Elgort also stopped by.
Come to think of it, that sorta does just sound like a regular day for Kendall and Gigi - doing high-profile modeling gigs and hanging out with hot guys.
Not a bad life. Not bad at all!
The video gives us a glimpse behind the scenes at the mag's 'Hollywood's New Brat Pack' shoot and they look like they have so much fun together, we totally want to be part of their crew!
We also wouldn't hate it if they carried selfie sticks around more often and shared the love on Instagram!
