They were in Dallas promoting their PacSun summer clothing line on Thursday.
But Kylie and Kendall Jenner were ready to relax and have fun as they hung out with their 'fwiends' on Friday.
The sisters shared photos on Instagram lounging on a couch in a funky red room with a bunch of their pals including Justin Bieber's BFF Lil Twist.
In one shot, the Keeping Up WIth The Kardashians stars sandwich Lil Twist on either side while laying on a large red couch.
Kendall, 18, shows off her long legs in skinny jeans and black boots while leaning up against the rapper and flashing a peace sign.
Her 16-year-old sister takes to the other side of the 21-year-old rapper decked out in a white T-shirt and tiny denim shorts as she looks away from the camera with her eyes closed.
