The One Direction alum approached Corden for the kiss after the duo had finished singing "Santa Claus Is Comin' To Town."

"Wow," Corden said, as Styles laughed. "I did not expect that for Christmas," he continued holding his hand to his mouth.

The Christmas edition of the popular late night show segment also featured Bruno Mars, The Foo Fighters, Miley Cyrus, Pink, Sam Smith, Fifth Harmony, Ed Sheeran and Kelly Clarkson singing the classic holiday tune.

The mashup was created during Corden's time spent with the singers during filming of his various Carpool Karaoke segments from throughout the year.

Corden previously featured Adele, Lady Gaga, Mariah Carey and others singing Carey's "All I Want for Christmas Is You" last year to ring in the holidays.
