When James Corden's Late Late Show segment Carpool Karaoke first aired it became an instant hit and it even got it's own spin off show.
Since Corden started featuring the segment on his talk show he has had some of the biggest names in music join him for a sing along - including Stevie Wonder, Mariah Carey, Britney Spears, Ed Sheeran and Adele.
But every now and then, a celebrity comes along that makes all the other guests look like insignificant nobodies by comparison.
Enter Céline Dion.
We were teased about her appearance nearly two months ago when James shared a selfie of the two of them on Instagram:

And last night we got to see Céline in all her glory when she joined James Corden for Carpool Karaoke.
From a Céline Dion version of Baby Shark to recreating a scene from Titanic - it's definitely one of our favourite Carpool Karaokes.
