On Tuesday Rumer Willis sang her very own version of Miley Cyrus' new single "Wrecking Ball" at the Sayers Club in Hollywood, and while we love the Rue, we kinda think she shoulda left this one to Ms. Cyrus.

Rumer is a regular performer at the venue (the previous week she sang "I Put a Spell on You" and "Son of a Preacher Man"), and her beau Jayson Blair and mom Demi Moore were there for that show. We wanna see her sing her own stuff though! She does have a great voice...
