On Dancing With the Stars Season 17, Week 9, Jack Osbourne and Cheryl Burke were challenged with the Viennese Waltz.

In the video package prior to the dance, Cheryl explained that ballroom has been Jack's strongest category, so this Viennese Waltz needs to be perfect. It was also Jack's birthday this week, so Cheryl planned him a little birthday and gave him a "best partner ever" award. Awww.

The Viennese Waltz was very nice. Jack really is good in hold, and Cheryl looked stunning. They moved quickly and smoothly. This was one of Jack's best dances. Maybe his very best so far.

Len loved the hold, and all the little things Jack got right. Bruno said "ballroom just flows out of you," and loved the way Jack spins. However, he told him to watch his hands, because sometimes they were a little like the Matrix. Carrie Ann said his whole journey was built on technique, and now he's flying, and has flair and flourish.

Score: 10, 10, 9
