Kourtney Kardashian ‘slept in her own sick’

Kourtney Kardashian "threw up in her bed" and "slept in it" whilst on vacation in Mexico.

The reality TV star is currently on holiday with her sister Kim and some of her closest pals in the five-star holiday resort of Casa Aramara, Punta Mita, where Kourtney has apparently been drinking far more than she’s able to handle.

Kim wrote on Twitter: "So I’m gonna give u guys a play by play of the trip so far…

"@kourtneykardash threw up in her bed 4 times and slept in it.

"@sarahrhoward tweaked her neck twerking (I will snap chat videos soon)

"@jenatkinhair spiked my Oreo shake to try to get me to not eat it because she’s fat shaming me.

"Nicole Reda had a 10 min black out & tried to fight @steph_shep

"@BrittGastineau skinny dipped solo and then disappeared for the two days. (sic)"

Kim also revealed her close friend Larsa Pippen has been trying to lead her astray during their vacation in Mexico.

She wrote: "@larsapippen tried to give me a "special" brownie and I threatened to sue her & the chef (sic)"

And after exposing Kourtney’s drunken antics, Kim later added: "Oh and @kourtneykardash won’t stop doing naked cart wheels."

Kim’s tweets came shortly after Kourtney admitted to throwing up "four or five times" during her post-birthday celebrations.

The TV star – who turned 38 on April 18 – admitted to drinking excessively during her belated birthday bash in Mexico.

Kourtney wrote on Twitter: "I may or may not have thrown up four times last night and slept in it. #birthdayvibes (sic)"

But last week, Kim marked her sister’s birthday by paying a glowing tribute to Kourtney.

She wrote on her website: "I’m so blessed to have you in my life. I love how close we were growing up – and still are today. I don’t know what I would do without you! Love you!"
