Sibling Rivalry With Derek Hough and Julianne Hough On ‘Lip Sync Battle’ [VIDEO]

Derek Hough and Julianne Hough took sibling rivalry to another level when they went head to head on this week’s Lip Sync Battle hosted by LL Cool J and his battle commentator Chrissy Teigen.

In the first round, Derek Hough started things off with a huge hit, “Can’t Hold Us” by Macklemore & Ryan Lewis feat. Ray Dalton, but sister Julianne had an even bigger surprise for her brother involving some bass. The other Hough tackled “All About That Bass” by Meghan Trainor, with some help from the lady “bringing booty back” herself.

The second round got a bit weird when Derek dressed in a platinum blonde wig sung Sia’s “Chandelier” and Julianne grooved to “I Just Had Sex” by The Lonely Island feat. Akon.

Last week’s battle pinned Malin Åkerman and Stephen Merchant against each other. Åkerman performed “Talk Dirty” by Jason Derülo and “Pour Some Sugar on Me” by Def Leppard. Merchant stripped down to leather chaps and performed “Dirrty” by Christina Aguilera then slowed it down with “Hero” by Enrique Iglesias. Stephen Merchant was victorious that battle.

Next week Salt-N-Pepa’s Cheryl James and Sandra Denton will battle it out and join the ranks of other celebrity guests that appeared on the show such as: Common, Terry Crews, Anne Hathaway, Anna Kendrick, and Dwayne Johnson.
