During her appearance, she spoke about the karaoke party she had for her birthday, which included a duet with sister Dakota Fanning to Carrie Underwood‘s “Before He Cheats” – and lots of alcohol.

“I threw up. A lot. In the Uber on the ride home,” she said.

“The story is a bit hazy for sure, but I’ve been told that the Uber driver was really nice. He was. And he had a stash of, like, throw up baggies in his car, so like, he obviously gets this a lot.”

Apparently, that wasn’t enough to handle the damage.

“I got the bag…but it was a lot, you know? We kept telling him that I ate bad fish: ‘It was, like, bad fish. Sorry, sorry. It was, like, bad fish’…it was like, he totally knows. I have glitter. Like, I’m probably wearing, like, a 21st birthday hat, you know?”

She recently revealed advice she received from Nicole Kidman. Find out what it was!
