Kylie took to Instagram to share a photo of her and Tyga cuddled up next to each other and mid-kiss on their private jet.

Apparently, it was a "last minute" adventure for the 19-year-old reality star and her beau, who later performed at Drai's Nightclub at The Cromwell.

Meanwhile in Los Angeles, Kylie's sisters, Kendall Jenner and Kim Kardashian West, were having a little trouble with their transportation while heading to Kanye West's "Famous" exhibition. Kim claimed that Uber, a popular car service app, had banned Kendall.

"Ugh I have to drive @KendallJenner around tonight bc she's banned from Uber!" the Selfish author tweeted. "Why @Uber?!?! She's a "model" passenger!!!!!"

On Saturday, however, an Uber source confirmed to ET that Kendall "has not been banned."
