Serena Williams took care of business Monday in front of a sold-out crowd at Arthur Ashe Stadium.

That crowd included a number of stars, all there to support Williams as she embarks on her final US Open run.

Daughter Olympia Ohanian was in attendance, sporting white beads just like her mother once did en route to her first US Open title in 1999.

Coco Gauff was also in attendance, after initially planning to watch the match from her hotel room.

“I was stretching, and, I was like, I have been coming to the US Open since I was 8 years old, every year, haven’t missed a year,” she said following her first-round win on Ashe. “Went from watching to playing, which is cool. We only really came to see Serena or Venus, to be honest.

“So then I was like, this is her final match. I feel like 8-year-old me would want to see this. Because I’m in the tournament usually I don’t like to stay at the site but this is a once-in-a-lifetime opportunity. So I said, I’ve gotta go and I heard that something special is going to happen.”

That something special included a 6-3, 6-3 win for Williams over Danka Kovinic, which ensured at least one more match for the superstar.

Afterward, she was honored on the court by Billie Jean King in a ceremony hosted by Gayle King. There was also a video montage, narrated by Oprah Winfrey.

“You are fearless. And you hate to lose, it is great,” Billie Jean King said. “You’ve taught our hearts and minds to be our authentic self, to use our voices — and dream big…Especially for women, and women of color.

“Most of all, thank you for sharing your journey with every single one of us.”

Actress Anna Deavere Smith was there alongside Queen Latifah.

Also among those in attendance were director Spike Lee, who helped with the coin toss, Vogue editor in chief Anna Wintour, former President Bill Clinton and many more.
