Contactmusic.com reports that Gomez told Seventeen magazine: "I questioned the way I looked, acted, sang, and wrote. I started becoming very stale with my music and I realised that I was doing things for other people.
"Then I turned 20, went through a really bad breakup, and realised I needed to pick up everything."
She says she had the urge to make "Come & Get It" "amazing".
