Watch Star-Studded Holiday ‘Carpool Karaoke’ with Harry Styles, Pink, Fifth Harmony, Kelly Clarkson, Bruno Mars & More

James Corden got way, way into the spirit in a new Christmas "Carpool Karaoke" video posted on Monday (Dec. 11) in which basically every star in the sky hopped into the passenger seat to spread some holiday cheer. Wearing their best/worst ugly sweaters, Corden and bandleader Reggie Watts got things going with a duo version of "Santa Claus is Coming to Town," which jumped to a quick-cut montage of the song featuring Sam Smith with Fifth Harmony, Harry Styles, Bruno Mars, P!nk, Kelly Clarkson, the Foo Figthers, Katy Perry, Miley Cyrus and Usher all chiming in.

So, basically, just about everyone who has taken a ride with Corden this year was there, yes, even Ed Sheeran. And sure, they were mostly wearing short-sleeved shirts and it was clearly warm and sunny in California, but if close your eyes and wish real hard you might just get a very unexpected treat at the end.
