After Ross brought up Kylie's recent bikini selfie that made waves on Instagram, she launched into a story about big sis Kim Kardashian.
"She walked into my room in Miami and was like, 'Oh my god, I don't have a bathing suit, Can I borrow one?'" Kylie said. "Cut to thirty minutes later, I walk in on her taking selfies and she's like, 'Yeah, you're not getting it back.'"
Hmm...reminds of us of that one episode of KUWTK when Kylie borrowed clothes from Kim's closet without asking. Should we call it even?
Kylie and Kendall have also decided to throw their own prom—watch the clip to hear the plans for their big bash!
#RichKids of Beverly Hills star Morgan Stewart also stopped by to discuss the season finale of her hit show.
