Harvey Fierstein has locked in a 12-week stint in “La Cage aux Folles” — the Broadway revival of the 1983 musical for which Fierstein penned the book.

Thesp (“Hairspray”) will replace Tony winner Douglas Hodge, donning the boa as drag performer Albin. Both Hodge and co-star Kelsey Grammer exit the show Feb. 13.

Fierstein has never before acted in “La Cage.” His most recent Main Stem stint was in 2008 in “A Catered Affair,” another musical for which he wrote the book.

As a scribe, Fierstein has two other musical projects in the works: a new stage version of “Newsies,” with tunes by Alan Menken and Jack Feldman, and an adaptation of 2005 pic “Kinky Boots” with music by Cyndi Lauper. Both could potentially hit the boards in fall 2011, according to Fierstein.

The current version of “La Cage,” which picked up the Tony for top tuner revival, is the Gotham incarnation of a production that began life in London at the Menier Chocolate Factory ahead of a successful West End run. Hodge appeared in both U.K. stagings.

Fierstein said he wouldn’t have fit into prior New York productions of the musical, which upped the glamour quotient of the proceedings. “In this one, the characters are a little bit more low-rent,” he said. “And I am not the most beautiful woman that ever walked on the stage.”

Sonia Friedman Prods. (“La Bete”), David Babani (a.d. of the Menier) and Fran and Barry Weissler (“Chicago”) lead the Broadway producing team of “La Cage,” which is helmed by Terry Johnson.

Fierstein is scheduled to be-gin his run in the show on Feb. 15.
