"Yummy" by Justin Bieber
The track — which was the first single from Bieber's Changes album — is a tribute to his sex life with Hailey. During an appearance on The Ellen DeGeneres Show in January, Ellen DeGeneres asked Bieber what he was thinking about when he wrote it, to which he casually replied, "My sex life." "It is what it is, right? I'm married," he added. "It is what it is."
