The U.S. Open is serving up some unexpected controversy.
Earlier this week, sports commentators Mary Carillo and Chanda Rubin were providing insight into Serena Williams' match against Anett Kontaveit at Arthur Ashe Stadium in New York.
But in between the match, the cameras panned to the audience, where a few famous faces including Dionne Warwick were cheering on Serena. Things got complicated, however, when Mary referred to the legendary singer as Gladys Knight, who was also in attendance at the match.
After the clip went viral on social media, Chanda explained what led to the misidentification.
"Too bad I was initially looking at the court (where Auntie Gladys was in the stands) and not our program monitor that showed Ms. Dionne..." she wrote on Twitter. "Mistake was immediately corrected."
As for what Dionne thinks of all the chatter off the court, she appeared to have a good sense of humor about it when she shared a message online.
"Hi, I'm Gladys Knight…" she wrote on Twitter Aug. 31. "And instead of taking that midnight train to Georgia, I won't walk on by but will say a little prayer for you."
Gladys would also comment on Twitter writing, "Dionne and I have been sisters for a long time and I hope she is as honored to be mistaken for me as I would be her. I'm sure it was an honest mistake. It was a blessing to be in the house to see Serena's greatness."

Back on Aug. 9, Serena penned a personal essay for Vogue where the tennis champion announced she's saying goodbye to the sport after one last tournament.
