Rumer Willis has had a bunch of small movie and TV roles in the past but has now turned to music.
She's currently on her Over The Love tour in the US and stopped by Sway in the Morning radio show during the week.
After chatting to the hosts for a while, she began to sing, and it's safe to say nobody thought she had a voice that amazing!
She blasted out Amy Winehouse's You Know I'm No Good and totally blew everyone away.
We think Rumer should definitely stick with music from now on.
