As the U.S. Open tournament kicked off Monday, a stadium was packed with celebrities to witness Serena Williams in what could be her final Grand Slam tournament.

The two watched intently, and Jackman snapped a few photos with his phone.

“Orange is the New Black” alum Laverne Cox and Beyoncé have similar fashion styles since fans mistook the actress for the “Renaissance” singer.
Cox took to Instagram Monday to address the mix-up and was a good sport about the mistaken identity.
“Not me getting mistaken for @Beyonce at the #USOpen tonight then trending on Twitter as the internet cackles over the mistaken identity,” the actress, 50, wrote.
She described the mix-up as “funny as hell,” concluding, “Go @serenawilliams #GOAT.”
