Kimberly Hébert Gregory, who was best known as the brash principal in HBO’s “Vice Principals,” has died. She was 52.

A cause of death was not immediately reported.

Gregory’s former husband, Chester Gregory, confirmed her death in an Instagram post.

“You Were Brilliance Embodied, A Black Woman Whose Mind Lit Every Room, Whose Presence Carried Both Fire And Grace,” he wrote. “So Much Than Ex-Wife, You Were My Friend. Our Son, The Song We Wrote Together, Is The Living Echo Of Your Light.”

Walton Goggins, the “White Lotus” breakout who co-starred with Gregory in “Vice Principals,” the HBO series that premiered in 2016 and lasted for two seasons, was among several performers who paid tribute on social media.

“We lost one of the best yesterday… one of the best I’ve ever worked with,” Goggins wrote in his Instagram post. “I had the honor… the good fortune of getting to know, getting to spend months working with this Queen on Vice Principals.”

Others who remembered Gregory included Kym Whitley, Leslie Odom Jr. and Jason Ritter.

Gregory’s character on “Vice Principals,” Dr. Belinda Brown, butted heads with rival high school vice principals Neal Gamby (show co-creator Danny McBride) and Lee Russell (Goggins).

In his review of “Vice Principals,” the Los Angeles Times’ Robert Lloyd wrote, “(Gregory’s) character is an invitation to political incorrectness — when told she graduated from Berkeley, Neal responds, ‘I’m pretty affirmative how she got in’ — but that attitude is more a side dish here than an entree; despite their conniving, these characters are lunkheads at worst.”

Her other credits included TV’s “The Chi” and “All Rise.”
