Kendall and Kylie Jenner are spilling secrets about their famous family!
The reality stars appeared on "The Tonight Show" Wednesday to promote their new book. Instead, the sisters were asked about big sister Kim Kardashian's lavish wedding in Italy.
The brunette beauties agreed the wedding was "amazing" and even shared their favorite moments. For Kylie, it was seeing Lana Del Rey perform. Kendall, meanwhile, told Jimmy Fallon that the pre-wedding fireworks at Versailles were "romantic."
The late night host also asked Kendall about her infamous teleprompter flub at the Billboard Music Awards, when she messed up 5 Seconds of Summer's introduction.
"Can you believe I did that?" Kendall asked. "I felt so bad. I can't even see you in front of my face right now." She then asked Fallon, "You can relate, probably, huh?"
"To screwing up?" he joked. "I never, ever, ever, screw up. Never."
Fallon then showed a highlight reel proving that he, too, has missed the mark a time or two.
Kendall will get her chance to redeem herself when she co-hosts the Much Music Video Awards with her little sister on June 15.
