Laverne Cox was mistaken for Beyoncé at the US Open, and her reaction was perfect

• Laverne Cox was mistaken for Beyoncé at the US Open.
• The mix-up quickly became a trending topic on Twitter.

Laverne Cox was excited that she was mistaken for Beyoncé at the US Open by "The Morning Show" actor Choni Francis.

On Monday, Francis posted a clip of the Cox rooting for Serena Williams to his Twitter account with the caption "#Beyoncé at the #USOpen." The tweet quickly took off, racking up 172,000 views in less than a day. The "Inventing Anna" actress was wearing a mask and her blonde hair pulled back in the short clip.

Cox posted a screenshot of Francis' tweet to her Instagram expressing delight at being mistaken for the "Heated" singer.

Author David Dennis Jr. tweeted that the mix-up was a "career highlight" and Cox agreed.

"Not me getting mistaken for @Beyonce at the #USOpen tonight then trending on Twitter as the internet cackles over the mistaken identity," wrote Cox. She also showed more support for Williams, who recently announced that this US Open would be her final tennis tournament before retiring.

Francis eventually tweeted apologizing for the mix-up and correctly identifying Cox.

"These tweets are funny as hell. Enjoy!!! Go @serenawilliams #GOAT," Cox added.

Friends of Cox chimed in to celebrate the flattering mix-up. "You DESERVE! You had queen's essence radiating from behind the mask," commented "iCarly" writer Franchesca Ramsey.

"You both do look alike! It was bound to happen," chimed in "Dear White People" actor Quei Tann.

Angelica Ross (of "Pose" and "American Horror Story" fame) wrote, "Funny as soon as I scrolled to this I was like 'that looks like Laverne.'"

It's no surprise that Cox is unbothered by the comparison. The "Orange is the New Black" star has been clear about her love for Queen Bey, telling Entertainment Tonight in 2020 that she worships the singer.
