“Dance Moms” instructor Abby Lee Miller is probably used to criticism for her harsh tactics on her Lifetime reality show. In 2012, when her show first aired, “Dancing With the Stars” professionals Derek Hough and Mark Ballas condemned Miller’s teaching style on Twitter. But as Monday night’s guest judge, it will be Miller’s duty to judge the pros and their celebrity partners on the next episode of “DWTS.”

After she heard about Hough and Ballas’ comments, where they essentially said her tactics were unmerited and abusive to children, Miller responded during an interview with OK Magazine on Saturday. Even though it has been nearly two years since the “DWTS” pros made inflammatory remarks against ALM, it doesn’t seem like she’s willing to let things go.

At first she seemingly joked, “I think I may make them drop and give me 50! Fifty push-ups.”

But Miller is seemingly going to be strict with Hough and Ballas. “You know what, payback is a bi*ch. You never know. You never, ever, ever know,” she said. “I teach my kids that all the time. We go to a competition, we check into the hotel, you get in the elevator, you’re in a restaurant. You don’t know who is judging the competition. You don’t know where they are or anything else.”

Then she added: “You always have to remember that if you say something negative, it’s going to come back to haunt you.”

Miller has admitted to already having a favorite in the bunch: 2014 Sochi Olympic gold medalist Meryl Davis, who is partnered with Maksim Chmerkovskiy. “She looks like a former prima ballerina,” Miller said. “She’s that good.”

“Dancing With the Stars” will air on ABC Monday at 8/7c. Tune in to see what happens when Miller meets Hough and Ballas face-to-face in front of the cameras for the first time.
