Jack Osbourne and Cheryl Burke channelled the free love of the 70s for a Cha Cha Cha during Dancing With the Stars 2013 Hollywood Night (Season 17, Week 3) tonight, Monday, September 30.

In the video package, Jack was very worried, and seemed to struggle to get the dance down. How did it go?

Well, it was certainly very 70s. Damn, their costumes were bright! Jack had good posture, but he did feel a little stiff and unsure of himself to us.

What did the judges think? Bruno said he loved the opening and attitude, but he said it needed more hip action. We agree. Carrie Ann said it was good but not his best, which Jack agreed with. She told him to watch his arms outside of hold. Len complimented his commitment but agreed that it needed more hip action.

His scores? 7, 7, 7 22/30.

What did you think of this dance? Were the judges spot on or totally off? Sound off in the comments below!
