Kylie Jenner Gets Oxygen Mask After Getting Altitude Sickness

Kylie Jenner wasn't feeling too hot on Tuesday, when she got altitude sickness while visiting South America with her BFF, Jordyn Woods.

The 19-year-old reality star ended up getting an oxygen mask, and documented the experience on Snapchat. Dressed in a red Adidas track suit, Kylie held up her mask and stayed calm, as a doctor explained that altitude sickness is common at an elevation of 11,000 feet.

Still, Kylie remained in good spirits, even sticking up her middle finger for the camera alongside a paramedic.

Meanwhile, Kylie's relationship with rapper Travis Scott is heating up. The pair was spotted on Sunday in Miami, Florida, at the River Yacht Club, looking affectionate as they hung out with pals.

A source close to Kylie tells ET that the two have been "spending time together nonstop."

"Kylie is having a lot of fun with Travis," the source says. "She needs it after such a rocky end with Tyga. Her friends are happy to see her so happy."
