Julianne Hough, former "Dancing With the Stars" pro and two-time winner, guest judged Monday's performances.
Hough had some choice words for her former competitive partner Mark Ballas following his foxtrot with Christina Milian.
"I really wanted to see you shine," Hough said. "I danced with Mark. You have to stand in front to make sure you're seen."
"We shine together," Milian responded.
According to Entertainment Weekly, Milian, who earned a 24 for her Foxtrot, addressed Hough's remarks once more, after the show, saying that she and her partner took the high road.
"As long as we know that we did a fantastic job, that makes me happy," Milian said.
For his part, Ballas said Hough's words were a bit of a shock. He said he tried to take it in stride, but admited to being a little bothered by the veiled attack.
"She put a little sting on me, but that's okay," Ballas said. "That's how she felt. It is what it is."
Hough appeared on the show for the first four seasons, but left the series to pursue a singing and acting career. Hough appears on the show frequently to support her older brother, Derek, who is currently paired with Amber Riley of "Glee".
Hough is slated to star in the upcoming film "Paradise".
