Mark Ballas sings and signs at Mohegan Sun

Changing focus: Mark Ballas is famous for his dancing, thanks to "Dancing with the Stars." When he comes to Mohegan Sun Friday, though, he'll be singing and playing guitar for an hour-long performance and then will do a signing.

Sound judgment: Music is nothing new for Ballas. Before he came to the Mohegan Sun a year ago, he told The Day he had been writing songs since he was 13 or 14. In fact, he went to a school where students had to sing, dance, act and play an instrument. He described his music as "singer-songwriter pop-rock stuff."

The marriage barely lasted longer than the lessons: Ballas had a small role in the most infamous wedding of last year. He reportedly gave some dance lessons to Kim Kardashian and Kris Humphries as they prepped for their reception. (Ballas had been Kardashian's partner on one season of "Dancing with the Stars.")
