The ladies chat up Luke Bryan, Pentatonix, Walk the Moon, Gigi Hadid (who says she's their biggest fan!), and 5 Seconds of Summer, who they ask, "Do you have any crushes on any people?" Well...Ellen, of course!
And the ladies even get a super special 5SOS souvenir – Michael Clifford's chewed up gum. Get that bad boy on eBay!
Their excitement over Meghan Trainor has to be the absolute cutest, plus they have a chat with Carrie Underwood, telling her that Shawn Mendes totes has a crush on her. Too bad she's married!
The guys of One Direction stopped in to talk with Sophia Grace and Rose - and when they asked, "Do you have any crushes on girls," the guys admitted to nothing. Harry said, "No, never," while Liam explained: "Girls are smelly."
