"He's the nicest person. He's so nice, he's so humble," she gushed over Williams. "He's so incredible and for every artist, producer, and anybody -- he is the cream of the crop. He's just amazing and he probably knows that he has that effect on people, so he makes an effort to make you feel welcome and at home, which I think is really nice."

Cabello has been teasing her new music on Instagram this week, revealing that the first official single, "Crying in the Club," will be released on Friday, May 19.

Earlier this year, Cabello spoke out about her exit from Fifth Harmony in an interview with Billboard, saying that she struggled to "just sing other people's words and be totally happy with that."

"You have to follow and honor that inner voice," she said. "I always encouraged the girls to do the same."
