Watch Christina Aguilera reveal the celeb Ryan Gosling used to have a crush on

He certainly has had pretty much every big star sitting next to him in the Carpool Karaoke car.

Christina was one of those musicians that we have been waiting to grace our karaoke screens! And finally... our wishes have come true!

Singing her 2002 hit Fighter, Christina described to James how to pull off her self-described 'growl' which she uses to make her songs sound amazing.

When we thought it couldn't get any better, Melissa McCarthy popped out of nowhere to join in on the fun.

However, the most prolific moment of Aguilera's sing-a-long car ride arrived when the star took a trip down memory lane to reminisce about what it was like to star on The All-New Mickey Mouse Club between 1989 and 1994 alongside Britney Spears, Justin Timberlake, Ryan Gosling and more. "I think there were crushes, but I wasn't on the train," she told Corden of the old gang. "But [Timberlake] had swag, I have to say. Ryan, he did have a crush on Britney. It was so cute, but she got Justin. They were a big ol' couple!"

We say it every time but James, can you please release a new Carpool Karaoke already?!
