What a trio!

Kendall Jenner and Hailey Bieber are the newest stars of Carpool Karaoke with James Corden, and they got quite the surprise when Miley Cyrus hopped in their ride to join in on the fun!

They were blasting Miley's hit "Party in the USA" when the singer popped up at the window, and the supermodels couldn't contain their excitement as they squealed with glee.

We wish they had spent a little less time belting it out, and a little more time having some girl gab. We want to know about Hails' secret wedding to the Biebs, and we're also curious about what's going on with Kenny and NBA star Ben Simmons?

"Kendall was spending time with Anwar [Hadid], but that ended and she started hanging out with Ben again. She hasn’t seen Anwar recently. When she’s not working, she’s been focusing her free time on Ben and flying to Philadelphia. They’re still not exclusive though," a source dished to People.

They might have kept it light, but we're willing to ask the tough questions! We asked Hailey if Justin still talks to Selena Gomez, and her reaction is priceless! Watch the below video!
