Turn-of-the-millennium R&B icons Monica and Brandy are finally teaming up for a tour.

Now 27 years out from their iconic duet, the singers revealed the long-wished-for “The Boy Is Mine” tour with a cinematic announcement on Tuesday.

In the “Silence of the Lambs”-tinged promo video, a young agent of some sort is led down to Brandy and Monica, who are being held in what a grizzled colleague calls the “Maximum Sound Asylum.”

“We can’t afford a ’98 or ’20 again,” he says, referring to the original drop and the duo’s pandemic-era virtual Verzuz song battle.

“These two could destroy the world as we know it if they hear each other,” he warns, while telling the newcomer that the artists can never be in the same key or “Lord help us all.”
