Cassie told HotNewHipHop that, for her "Rock a Bye Baby" mixtape, she received rap lessons from Los.

"I worked on that with my labelmate Los and he just really coached me through it, and I was like 'Los I can not believe you have me rapping this fast, I never thought I could move my mouth this fast,'" she said.

Everybody's letting it marinate, but even when I played that record and "Bad B******" for one of my friends wh'ís known me since I first started in the music industry was like, 'Wait, this is Esther Dean.' Everyone has been like, 'What the hell? Where did you come up sounding like that? I don't ever remember you being loud and boisterous.' I'm like, 'I know, I'm so laid back in real life.'"
