As Serena Williams wowed at the US Open, announcers called attention to the many celebrities who came out to support the tennis champ, but they seemingly couldn't tell iconic singers Dionne Warwick and Gladys Knight apart.
On Wednesday (August 31), ESPN broadcasters Mary Carillo and Chanda Rubin were commentating during Williams' match against the world's No. 2 player Anett Kontaveit and misidentified Warwick as Knight, who was also in attendance at Arthur Ashe Stadium, per TMZ.
"Got some more stars," Rubin said as the camera panned to Warwick.
"Gladys Knight," Carillo replied, to which Rubin repeated back.
"Hello!" Carillo said.
A Twitter user shared a clip of the moment, writing "Unacceptable, from both of them."
Rubin tweeted out her response to the video of the apparent slip-up that's garnered over 2 million views.
“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… mistake was immediately corrected,” Rubin explained.
On Thursday (September 1), Warwick joked about being mistaken for Knight on Twitter.
"Hi, I’m Gladys Knight… and instead of taking that midnight train to Georgia, I won’t walk on by but will say a little prayer for you," Warwick wrote.
Other stars who attended Williams' match included Tiger Woods, Spike Lee, Anna Wintour, La La Anthony, and more, per TMZ.
After defeating Kontaveit in an upset victory, Williams has advanced to the third round of the US Open, where she will faceoff against Ajla Tomljanović.
