The GRAMMY winner says her fool-proof way of knowing if her songs will be a hit is when she starts to tear up to her own lyrics. "In order for me to feel confident with one of my songs it has to really move me," she told The New York Times. "That's how I know that I've written a good song for myself -- it's when I start crying."
She doesn't just get a little choked up either. Adele says she has an all-out cry fest. "It's when I just break out in [expletive] tears in the vocal booth or in the studio," she admitted, "and I'll need a moment to myself."
While Adele's new hit, "Hello," has broken numerous records since its Oct. 23 release, the singer first thought it had flopped. Upon checking her Twitter immediately after "Hello" was unveiled, she saw only three tweets in response to the track.
"I was like, 'Oh, no, I've missed my window,'" the 27-year-old recalled. "'Oh, no, it's too late. The comeback's gone. No one cares.'"
It wasn't until her boyfriend and the father of her child, Simon Konecki, accompanied her at the computer that she started to see the thousands of messages coming through about her new song.
Adele confessed that she was "scared" to even attempt a new album before the success of her single. "I didn't think I had it in me to write another record. I didn't know if I should," she said. "Because of how successful 21 was, I thought, 'Maybe everyone's happy with that being the last thing from me. Maybe I should bow out on a high.'"
