The youngest Keeping Up With the Kardashians stars shot an episode of E!'s Fashion Police on Thursday and shared an on-set photo.
"Just wrapped #FashionPolice with the hilarious Joan Rivers and of course the amazing @kellyosbourne @georgekotsi and @giulianarancic," she Instagrammed.
The stylish sisters know a few things about fashion considering they have their own PacSun line as well as a jewelry collection called Metal Haven.
We wonder if they'll comment on their sisters or mom's style on the show!
Kendall's also been working on her fitness (perhaps for rumored beau Harry Styles?) and shared a shot of herself and Kim showing off their famous butts at the gym.
"Barging in on Kim's booty selfie," she captioned their pic.
Looking good, ladies!
