Watch out, Mariah, Cher and Lady Gaga — some bigger divas are set to slay on the Las Vegas strip.

A gag-worthy collection of “RuPaul’s Drag Race” villains and victors will bring some shade to sunny Sin City during a residency at the Flamingo Las Vegas in early 2020.

To quote Seasons 2 and 3 castoff Shangela: Halleloo!

Billed as a “most sickening eleganza extravaganza,” “RuPaul’s Drag Race Live!” will include dancing, comedy, lip-syncing, live tunes, fierce fashion and plenty of spilled tea and death drops for the most die-hard of fans.

” ‘RuPaul’s Drag Race Live!’ is an immersive, interactive thrill-ride for everyone who loves to laugh, dance and sing along when a fabulous drag queen shakes her padded ass on stage,” said Emmy winner RuPaul, who Ru-vealed the residency at his annual, three-day DragCon NYC at Jacob K. Javits Convention Center on Saturday morning.

No exact premiere date was announced, but a rotating cast of seven queens will perform at 9:30 p.m. Tuesday, Thursday, Friday, Saturday and Sunday starting in January. Sashaying across the stage will be Season 11 winner Yvie Oddly; Season 11 contestant Kahanna Montrese; New Yorker and Season 10 winner Aquaria; Asia O’Hara and Kameron Michaels (Season 10); Eureka O’Hara (Seasons 10 and 9); Derrick Barry, Kim Chi and Naomi Smalls (Season 8); Coco Montrese (Season 5); India Ferrah (Season 3); and Shannel (Season 1).

Fans may remember that Aquaria (née Giovanni Palandrani), 23, was the first drag queen ever to walk the red carpet at the Met Gala in May.

“I’m a very femme gay boy, so what better way to express that than through drag?” the primped, plucked and tucked Aquaria told The Post in 2018. “It truly is the greatest mix of art forms.”

Pre-sale tickets will be available at 1 p.m. ET Tuesday at rupaulsdragracelive.com. Caesars Rewards and loyalty members and Live Nation and Ticketmaster customers can purchase tickets starting at 1 p.m. ET Wednesday at ticketmaster.com/dragracevegas, with general sale tickets starting at $49 available at 1 p.m. ET Friday.

The show will be directed by RuPaul and filmmaker Jamal Sims (“When the Beat Drops”) and produced by World of Wonder and Voss Events. No word yet on whether RuPaul himself will strut his stuff.
