James Corden Says He Wasn't Snubbed By Rolling Stones

James Corden isn't always the jolly host he plays on TV ... and that's probably 'cause he can't always get the guests he wants for his sing-along shtick.

We got James leaving Craig's Sunday where he got short and defensive when asked what songs he would have sung with The Rolling Stones for "Carpool Karaoke" -- assuming the rumors he got snubbed by them are true.
