'Dancing With the Stars' Derek Hough and Mark Ballas take issue with 'Dance Moms' Abby Lee Miller

"Dancing With the Stars" coaches Derek Hough and Mark Ballas aren't exactly fans of the Lifetime reality show "Dance Moms." and its star, Abby Lee Miller. They've taken to Twitter to express their displeasure.

"I'm sorry but this Dance mom show is straight up abusive," Hough tweeted Wednesday. "Kids Run !!!!!! It ain't right. Child abuse isn't right. I'm livid right now." He also said, "[There's] nothing productive about screaming and making little girls cry over being on the wrong foot." We're cheering from where we're sitting, Derek!

Ballas was none too please either, tweeting, "Watching dance moms.... Anyone watch this show?? This teacher lady is crazy... Completely wrong attitude towards the kids, [it's] embarrassing." He continued "correct teaching is patience, discipline, confidence building and love" and tweeted that Miller "needs a reality check. Dance is meant to be fun and inspirational, not abusive. Kids are impressionable and I don't want young children being afraid to take up dance because of this lady.
