We've always been fans of carpool karaoke on the "The Late Late Show with James Corden," but this episode with singer Gwen Stefani was a jam-packed session.
The 46-year-old "Hollaback Girl" songstress teamed up with host James Corden on Wednesday for another edition of good (and hilarious) in-car singing.
From singing Stefani's hits like "Rich Girl" and "The Sweet Escape," Corden also asks the singer about her secrets to looking young (because let's be real, she hasn't aged), the use of emojis and her relationship with country singer Blake Shelton.
But the video takes a quick turn when Corden realizes he needs more passengers to actually take the carpool lane. Who does he call up? Two celebrities, of course. Check out who joins the duo in the video above — seriously, this is one karaoke ride we want to be a part of.ALSO ON HUFFPOST:
