You may or may not know who Khia is. But that hardly matters, and she wouldn't care anyway.
If you're in the know, though, she's the rapper/singer behind 2002's then-raunchy R&B hit "My Neck, My Back." Her career hasn't posted a single since that has risen to the success of "Neck," but that hasn't stopped her from laying into Serena Williams and Beyoncé both over their "Sorry" video collaboration for the latter's Lemonade.
The visual album was revealed last weekend has sold more than 500,000 copies sold to date and looked to be buzzing to No. 1 on *Billboard*'s Hot 200 album chart. Serena's appearance was the most obvious and extended celebrity sighting of a few that populate Lemonade. Khia's complaint about it was catalyzed by the depiction of Beyoncé perched on a throne while Serena moves and dances—sometimes suggestively—through the halls of the video's setting, as well as around and in front of said throne.
In a no-holds-barred appearance on an online Atlanta radio station, Khia took the pair to task, calling the video concept "tired" and saying, among other things, it "just made black people look bad as hell." She didn't simply name names. She also called them, terming Serena a "jester" and a "prop" for appearing as she did in the video. A tirade of additional and more explicit criticisms followed during her extended rant. [NSWF video here, here, here and here.]
Khia appears to have missed the video's built-in reference, obvious to those who follow Serena and sports on the whole. The throne in "Sorry" alludes to Serena's appearance on the cover of Sports Illustrated in December 2015, when the magazine bestowed its Sportsperson of the Year title on her.
