Kim Kardashian Officially "Afraid Of Heights" After Crying on Roller Coaster

What started out as a fun trip to an amusement park took a dramatic turn when Kim Kardashian broke down in tears while riding a roller coaster with her sister, Kendall Jenner, and her boyfriend, Kanye West, at Six Flags Magic Mountain Amusement Park in Santa Clarita, California on Tuesday (July 17).

After safely getting back on her own two feet, the "Keeping Up with the Kardashians" star tweeted a picture of herself from the ride which shows her mouth wide open, her eyes glues shut and her hands gripping the harness and - although the ride caused Kendall's long locks to whip around - Kim's coif stayed neatly held together in a high bun.

Proving a roller coaster can create a mix of emotions, Kim tweeted with the picture, "Magic Mountain fun today!!! Kendall screaming, Kanye laughing & me crying!"

Before tweeting a close up of her terrified face, the 31-year-old showed she was still amused by her reaction, writing, "Mannnn my crying face! LOL" while then following up by poking fun at herself with, "Another ugly infamous cry face for the records".

Kendall seemed to get a kick out of her big sister's reaction, as well, by messaging to Kim, "LOL cry babyyy!" after Kim admitted to her more than 15 million twitter fans, "I officially am afraid of heights now."

However, when Kim tweeted to Kendall, "You cried too on one ride!!", Kendall had to defend herself, responding with, "no I had something In my eyeee! duh".
