When it comes to #BlackGirlMagic, greatness is unlimited.
On Tuesday night, Serena Williams took to her Twitter account, gushing over a new Nike ad entitled #UnlimitedGreatness, in which Olympic heroes Simone Biles, Gabrielle Douglas, Nia Ali and many more show her the utmost love and respect.
"She's inspired me to go out there and just be so fierce," Douglas says in the clip.
Added Biles: "I think Serena has inspired everyone through our whole careers because she's been so dominant. It's definitely inspiring watching her."
Ali chimed in with: "I just want to congratulate you first and foremost and just to let you know how beautiful your strength is. You could be aggressive on the court and you could be fierce and then you come out here and you slay!"
In addition to the ladies, the ad also has the likes of sprinting great Michael Johnson, baseball Hall of Famer Ken Griffey Jr., Kevin Hart and Spike Lee singing the tennis queen's high praises.
No wonder Serena was so touched by the commercial, which she was surprised with by the Swoosh.
Take a look at the epic ad.
The clip also has track and field star Sanya Richards-Ross recalling Serena's famous quote, in which she corrected a reporter from calling her one of the greatest female athletes of all time to flat out one of the greatest athletes of all time, period.
Coincidentally, that inspirational quote has been plastered on a wall in Brooklyn in the form of a Nike billboard.
The debut of the Nike ad came in conjunction with Williams defeating Ekaterina Makarova, 6-3, 6-3, in the first-round action of the U.S. Open in New York City on Tuesday.
If Serena wins the tournament, she'll surpass Steffi Graf's 22 Grand Slam titles to pull within one of Margaret Court's 24 for the most major women's singles championships in tennis history.
