Meghan Trainor's Upcoming Single Was Written Last Minute

Meghan Trainor attends a conversation with Epic Records head L.A. Reid about his new memoir on Tuesday (February 2) at 92Y in New York City.

The 22-year-old singer wrote her upcoming single “No” in one day just before her album was finalized, she told Fuse.

“I went to the studio and I wrote a big anthem that was called ‘No,’” Meghan said. “And I came back to L.A. Reid the next day, with it all produced and written, and I played it for him and he played it 24 times at 9:00 p.m. at night, because he loved it so much. He was like, ‘There it is.’”
