Now James Corden looks set to welcome one his biggest guests to Carpool Karaoke yet: Madonna.
His producer, Ben Winston, hinted at Madge's impending appearance on the show when he posted a picture of her and James on Twitter.
The singer herself also shared the snap on Instagram with the caption: "Riding around Manhattan with this Hunk of Burning Love."
We simply cannot wait for James to get into the groove alongside Madonna.
