Last month, Hough, 25, wore blackface as part of her Crazy Eyes costume — a tribute to the beloved character played by Aduba — as part of a group who dressed up as various characters from the Netflix series.
"I think maybe it was an unfortunate event, but she apologized and I feel like we can all move on," Aduba told E! News.
Hough quickly apologized after the incident, taking to Twitter to show her remorse. "I am a huge fan of the show Orange is the New Black, actress Uzo Aduba, and the character she has created," she wrote. "It certainly was never my intention to be disrespectful or demeaning to anyone in any way. I realize my costume hurt and offended people and I truly apologize."
