Just in case you didn't think Taylor Swift was a hoot and a half (industry term), here's Alana Haim to set you straight.

MTV News caught up with the littlest Haim and her older sisters, Este and Danielle, at the 57th Annual Grammy Awards on Sunday (Feb. 8), and -- OF COURSE -- the conversation took a turn for the Tay.

"She is honestly the funniest person I have ever met in my life," Alana told MTV red carpet correspondents Christina Garibaldi and Todrick Hall.

The Best New Artist nominee continued: "She is so hilarious. She makes me laugh constantly, and we're just so stoked to go on tour with her -- it's like a whirlwind of emotion."
