John Travolta made a hugely embarrassing mistake when he introduced Broadway star Idina Menzel -- who performed the biggest hit with the under-10 crowd these days, "Let It Go" from "Frozen," a Best Original Song nominee. He absolutely butchered her name, calling her "Adele Dazeem." What the what?! Seriously, John? How do you even get that mispronunciation out of her name? Host Ellen DeGeneres tried to make up for it after the performance ended by saying Idina's full name -- twice. We just hope John apologizes.
