'DWTS' Cheryl Burke: Cirque du Soleil character dance may help Ryan Lochte shine in Viennese Waltz

"Dancing With The Stars" Cheryl Burke praised partner #Ryan Lochte for improved scores last week. The couple's Cha-Cha beat James Hinchcliffe and Sharna Burgess in a dance-off for immunity, but just barely. Burke says Lochte needs to get his head in the game for Cirque du Soleil Week on "DWTS." And the character dance Viennese Waltz just might give Lochte the confidence boost he needs to step up his dancing.   'DWTS' Cheryl Burke: Cirque du Soleil, Cha-Cha may let Ryan Lochte shine in Viennese Waltz
