It's been a while since our last Carpool Karaoke, but this one's been worth the wait.

In the 8-minute episode above, James Corden and Christina Aguilera slay some "Fighter" before talking old Mickey Mouse Club crushes (apparently Ryan Gosling had a thing for Britney back in the day) and then absolutely crushing a heartfelt rendition of "Beautiful". Melissa McCarthy even gets involved at one point.

The biggest, indisputable takeaway though? Christina Aguilera's voice is just ridiculously, ridiculously good.
