Lady Gaga Appears On 'Carpool Karaoke'

(Radio.com) By Tuesday evening, Lady Gaga fans knew the pop star was going to be joining James Corden for The Late Late Show segment "Carpool Karaoke."

But viewers got a bigger treat than they expected when the pop star showed up at the show's opening as 'Lady Haha" and delivered the opening monologue.

Acting as though he had to rush to his gig, Corden arrived on stage half-dressed and invited the singer to join the band to sing "A-Yo" from her new album Joanne.

Then it was time for Carpool Karaoke. The duo kicked it off with Ludacris' famous lyrics, "Move b�-, Get out of the way" ("Move B�- Get Out Da Way"), then they did some not-so-choreographed dancing to "Perfect Illusion" and "Bad Romance" before Gaga took the wheel. Watch it here.
