Miley Cyrus Can't Be Tamed, but she CAN be spanked, especially after engaging in risque behavior right in front of her mom!

In a new clip released online (which will apparently be included in the Can't Be Tamed DVD) backstage at her recent concert at London's O2 stadium, Miley mouthed off to her mom Tish, who responded by spanking her seventeen-year-old! Miley then did a booty-shaking dance right in front of Tish, who said, "I will spank you!”

But Miley didn't stop with her sexually suggestive behavior -- and as she headed out to the stage, she sang a lyric from the Justin Timberlake song, “Ayo Technology”, which goes “Why don’t you sit down on top of me?”

Sorry, Tish, but we don't think a spanking is going to help at this point!
