Dancing With the Stars 2014: Season 18, Week 4 Performance Pics

Dancing With the Stars Season 18, Week 4 really shook things up in the ballroom. And we're not just talking about all of the shimmying and butt-shaking.

The stars and pros participated in the Switch Up challenge, where each star was paired with a new pro. Scandalous, eh? Some of the dances went over well (we're looking at you, Meryl and Val), while others didn't get the best critique. Julianne Hough even told Maksim Chmerkovskiy that he phoned in Danica McKellar's Jive. Yikes!

This was the first time DWTS did the Switch Up challenge, and it definitely did a great job at sparking up some drama and competition.

Be sure to watch all of the videos from the episode and check out photos of all of the performances. Did you like the new challenge, or do you hope it was a one time thing? Sound off in the comments!
