Kendall Jenner's First Kiss Happened In A Shower!

Kendall Jenner heads out of The Nice Guy restaurant after meeting up with Justin Bieber in Los Angeles on Tuesday night (December 15).

The 20-year-old model headed straight for her waiting ride after grabbing a bite to eat.

Kendall just recently wrote about experiencing her first kiss — and it happened in a shower!

“This is a good one! It happened in a shower. I know that sounds crazy, but it wasn’t what you’d think. I was with one of my friends from elementary school, Jessica�this was probably fifth grade. The kiss was with a kid I had THE biggest crush on�shout out to Chad Wilcox! I crushed on him for so long. I was obsessed. Jessica actually did, too, haha. So, we were like, ‘Let’s invite him over to hang out’,” Kendall wrote on her official website.

She continued, “We were at my mom’s house and played Truth or Dare�of course, the point of that was to kiss each other. ;) Kylie was so nosy, so we kept going to secret places like the trampoline�and Kylie kept spying and, like, popping out of trees, lol. We were like, “Go away!” and she was like, “What are you doing?!?” She followed us to the living room, then the bedroom. We even locked her out with a chair under the doorknob and she found her way in. So annoying. She kept saying, “You’re being shady!”

“We ended up in my bathroom because it was the only room with a lock! Finally, we got to the Truth or Dare kissing. Jessica and I didn’t want to do it in front of each other so Chad and I went in the shower behind the curtain. And that’s how the magic of my first kiss went down! ;)”
