The Simon Cowell-created British boy band had everyone gushing—and dancing—at the Kids' Choice Awards on Saturday.
Read on to find out what some of your fave celebs have to say about the five lads from across the pond.
"I think they're awesome," Victoria Justice told me. "They're supercool. They're super down to earth and I think they're really talented…The fact that they're from the U.K. and have those accents, it's very appealing to a lot of people and they're all supercute guys."
Those guys, if you don't know by now, are Liam Payne, Louis Tomlinson, Niall Horan, Harry Styles and Zayn Malik. Their album Up All Night made Billboard history by becoming the first debut album by a British group to enter the chart at No. 1.
X Factor star Rachel Crow met them recently in New York City. "Their songs are in my head all the time," she said.
Their hit "What Makes You Beautiful" is her favorite. "I pretend they're singing to me," Crow smiled.
During 1D's Kids' Choice performance, Gomez, Swift and even the First Lady got out of their seats to dance.
Glee's Chris Colfer was walking the orange arrivals carpet just a few feet in front of the guys. It wasn't easy interviewing anyone when 1D was around, because the screaming was deafening. Colfer cracked, "Maybe we'll do a One Direction tribute episode."
And 1D seems to be on a campaign to work with Bruno Mars. They recently told E! News they wanted to collaborate with the "Grenade" hitmaker and reiterated it on Saturday. "If we could work with anyone in the world, I think we'd pick Bruno Mars," Harry said. "He's just incredible. He's got the voice. And he's a great performer."
And if that doesn't work out, Louis joked, "Susan Boyle."
