DANCING WITH THE STARS 'Switches Up' More Than Dancing After Technical Problems

Eight remaining couples hit the dance floor and faced an exciting new challenge on "Dancing with the Stars" tonight, October 21, when they competed in an individual dance style they had not yet done, as well as taking part in the first-ever "Switch-Up Challenge."

But dancing wasn't the only thing Being "switched up" this evening -- People reports that technical problems made many viewers's votes invalid, and as a result, no one was eliminated this week.

"Last week, at the end of the show we had a technical problem," host Tom Bergeron said. "The incorrect phone numbers were shown. And they have resulted in some votes accidentally cast for the wrong couple. So, in fairness we have decided to discard all the viewer votes and not eliminate anyone this week."

Hosts Bergeron and Brooke Burke Charvet revealed after announcing which couples were in the bottom two -- Jack Osbourne & Cheryl Burke and Bill Engvall & Emma Slater -- that both duos were safe.

Hosted by Emmy Award-winner Bergeron ("America's Funniest Home Videos") and Burke-Charvet ("Dancing with the Stars" Season 7 Champion), "Dancing with the Stars" is the hit series in which celebrities perform choreographed dance routines which are judged by renowned ballroom judge Len Goodman and dancer/choreographers Bruno Tonioli and Carrie Ann Inaba.
