There’s Broadway buzz that Aaron Tveit and Sutton Foster will replace Josh Groban and Annaleigh Ashford in the revival of “Sweeney Todd.”

A source told us Foster and Tveit will star next in the famously dark Stephen Sondheim musical about “The Demon Barber of Fleet Street,” after Groban and Ashford take their final bows Jan. 14.

There have already been rumblings on social media of the new duo, and sources now tell us the news is imminent after the show announced its run has been extended at the Lunt-Fontanne Theatre through spring 2024.

Groban and Ashford starred in the show for a 46-week run, and the production racked up eight Tony Awards and two wins.

The show also stars Gaten Matarazzo from “Stranger Things.”

Foster most recently starred in “The Music Man” with Hugh Jackman, and Tveit is known for his long-running role in “Moulin Rouge! The Musical.”

The stars previously appeared together at Sydney’s Theatre Royal in 2016 for a concert called “Defying Gravity: The Songs of Stephen Schwartz.”

Reps for the stars, and the show, did not get back to us.

“Sweeney Todd” originally opened on Broadway in 1979. It was also adapted into a 2007 Tim Burton film, with Johnny Depp in the lead role.

The Post called the show, “one of the greatest musicals ever written,” and said of the current production, “Groban is not the menacing, feral Todd that Len Cariou and Michael Cerveris were, but a calmer chap with an ax to grind,” and, “Ashford is a remarkably gifted comedienne.”
