Wherever Serena Williams goes, Beyoncé and Jay-Z are sure to follow.
After supporting their friend at Wimbledon in July, the musicians watched Williams compete in the U.S. Open in New York City Thursday. Enjoying a kid-free night out (their 4-year-old daughter Blue Ivy Carter was presumably at home), the couple sat one row behind Williams' family. Throughout the evening, the "Crazy in Love" collaborators oohed and aahed in the stands.
Williams faced Vania King, beating her fellow American tennis pro 6 to 3.
Beyoncé and Jay Z's presence didn't go unnoticed.
"I looked up and was like, 'Oh s--t! Beyoncé is watching,'" King told ESPN.
Williams invited the power couple to watch her compete. "Usually when people are there, I try to play better, especially if they're famous and they're doing so great at their job," the athlete said after the match. "It's like I want to show them that I'm good at my job, too—minus today."
The tennis pro has been dealing with a right shoulder injury, which hurt her performance at the Rio Olympics. Thankfully, Williams said it's been "stable" during the U.S. Open. "I've just got to keep it like that. It's two matches in, and usually you want to be able to play seven matches. It's not even close to the halfway point," she said. "I definitely want to keep it as good as it can be."
Earlier this year, Williams made a cameo in Beyoncé's "Sorry" music video, and on Sunday, she introduced her performance at the 2016 MTV VMAs. "I've known Bey for a long time," Williams told WSJ. magazine in June, joking that that the choreography made her "really sore!"
A little soreness didn't stop Williams from releasing her own Delta dance video Thursday. "Dancing in the Beyoncé video was obviously a lot of fun. I remember being super sore after because I was down the whole time, you know, kind of twerking a lot," she told the Associated Press last week. "I was able to work a lot with her choreographers...and I really learned so much just about my body movement and also different styles of movement to do."
