Who knew they were so wild?!

Kim is currently on a girls' trip in Mexico with sister Kourtney and their pals, and the reality star decided to share some behind-the-scenes details from their vacay.

“So I’m gonna give you guys a play by play of the trip so far," she tweeted. "kourtneykardash threw up in her bed 4 times and slept in it. Nicole Reda had a 10 min black out & tried to fight @steph_shep. @BrittGastineau skinny dipped solo and then disappeared for the two days," she began.

"@jenatkinhair spiked my Oreo shake to try to get me to not eat it because she's fat shaming me. @larsapippen tried to give me a "special" brownie and I threatened to sue her & the chef. @jOYCEBONELLi put nipple clamps on @ForeverMalika. Oh and @kourtneykardash won't stop doing naked cart wheels," she continued.

And they say Scott Disick is out of control?!
