James Corden has had his share of run ins with music icons with his show 'Carpool Karoke.' However, his program The Late Late Show brought him the opportunity to meet with a music legend. Cher joined Corden on Thursday night's episode and the pair did a rendition of her famous song "I Got You Babe." There was only a minor glitch when Corden came out dressed as Cher as well instead of her late partner Sonny. "i'm commited to it now," Corden says.
