On being embarrassed to sing "Cool for the Summer" at a state dinner at the White House: "I left it out of the set list because I was like, 'Surely it's too inappropriate for the White House,' and then [the First Lady] requested it. And so I was like, 'OK, here we go!' [Laughs.] Like, 'Tell me what you want, what you like, it's OK.' . . . I didn't look [the President] in the eyes. And I didn't look her in the eyes, either. When I normally say, 'Shh, don't tell your mother,' I changed the lyric to 'Shh, don't tell the President.'"
