Dancing With the Stars: All-Star couples tweeting about how they like surprise dances on 'DWTS'

LOS ANGELES - Week four of “Dancing with the Stars” should throw the All-Stars for a loop.

They have been practicing for dances that many have never done before.

But so far, many have been tweeting about how they are handling these new dances.
