Mark Ballas is a Dancing with the Stars newbie. But the professional has spent years performing in England and is well-respected in his field. He partnered with Sabrina Bryan on season five and Kristi Yamaguchi on season six.
On season seven, it's all about Kim Kardashian. He teamed with the former sex tape star on the show. They didn't last long, however.
But Ballas fared far better on season eight, partnering with gymnast Shawn Johnson.
