Drinking the night away! Kendall Jenner imbibed so much at her 21st birthday party Wednesday night that the model forgot she received a Rolls-Royce as a present, sister Khloé Kardashian revealed on Jimmy Kimmel Live!

“This morning I was like, ‘Holy crap! … Do you remember? That’s so cool you got this car! How’d you get it home?’” the Good American jeans designer, 32, said told Kimmel, 48, Thursday, November 3. “She was like ‘Oh, my God, I forgot I got a car!’ That’s how drunk she was.”

The reality star documented the grand gesture on Snapchat November 2, showing Jenner grinning from ear to ear as she received the luxury car, which September’s Vogue cover girl obtained under odd circumstances while celebrating at West Hollywood’s Delilah nightclub.

“We go outside and there’s a Rolls-Royce and this man standing there,” Kardashian continued. “I was like, ‘What’s the, who’s the gift, the guy or the car?’ I was so confused. And then this guy just hands Kendall a pair of keys to this car and I was like, ‘Do we even know who this guy is?’ He’s some kind of prince.”

Celebrity guests at the shindig including Hailey Baldwin, Jordan Clarkson, Scott Disick, brother-in-law Kanye West, mom Kris Jenner, dad Caitlyn Jenner, and sisters Kylie Jenner and Kourtney and Kim Kardashian joined in the festivities, which started with dinner at Catch. Khloé, dating NBA player Tristan Thompson since August, told Kimmel that the birthday girl threw an afterparty at her Hollywood Hills mansion, which happens to neighbor Kimmel’s home.

“I saw that something was going on over there, but I was watching the baseball game,” said the father of three, referring to the World Series' Game 7 in which the Chicago Cubs won their first championship since 1908. “I feel like they were not. They were the only people in America not watching the game.”
