The dynamic duo was participating in a photo shoot Friday for their spring clothing line, but instead of working they decided to horse around! Kylie shared two videos on her Instagram page of their fun day on set, and in one video she and Kendall twerked and whipped their hair instead of taking pictures of the collection. In the second video they stand on a dolly and do backwards leg kicks.
The E! reality TV stars must have been a little bit delirious because the only caption Kylie could come up with was "Lol," so they must have had a great time together. With Kendall's modeling career and Kylie's busy schedule, the sisters have said it can be hard to meet up sometimes, so they're probably happy they got to goof around together!
