Kendall Jenner doesn't seem like the type of girl to kiss and tell, but the "Keeping Up With the Kardashians" star dished details about her first-ever kiss in a new blog post on her app and website, People reported. The Victoria's Secret model even gave a shout-out to the boy she shared her first kiss with and explained how little sister Kylie almost ruined her moment.

"It happened in a shower. I know that sounds crazy, but it wasn't what you'd think," Kendall wrote, according to an excerpt from the post obtained by Marie Claire.

The kiss happened when Kendall was "probably" in fifth grade. She was at her mother Kris's home with her elementary school friend Jessica, and the girls were gushing over their mutual crush, Chad Wilcox. The girls invited Wilcox over for a game of truth or dare.

"Of course, the point of that was to kiss each other," Kendall continued. "Kylie was so nosy, so we kept going to secret places like the trampoline [....] 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! ;)"

Kylie also dished details about her first kiss on her app, Entertainment Tonight reported. The 18-year-old reality star chose to reveal that she shared her first kiss with fellow fourth grader Matthew McGraw in a video clip posted to her website in October.
