New York ? Two of America’s baddest bad girls are getting ready to rumble.

The network is billing the bout between Tonya Harding and Amy Fisher as “the battle of the bad girls.” The pugilistic divas will face off on “Celebrity Boxing,” a Fox special scheduled to air March 13.

Also on the special, former “Brady Bunch” star Barry Williams will be pitted against Danny Bonaduce, once part of TV’s “Partridge Family.”

The network said the fights will be real, each lasting three rounds.

Harding gained notoriety when, in January 1994, the figure-skating champ was involved in a bungled plot hatched by her ex-husband to disable skating rival Nancy Kerrigan. Kerrigan took the silver medal while Harding, who finished eighth in the Winter Olympics, later pleaded guilty to conspiracy.

Fisher made headlines as “the Long Island Lolita” in 1992 when, as a teen-ager having an affair with auto mechanic Joey Buttafuoco, she shot and wounded Buttafuoco’s wife. Fisher served almost seven years in prison.

A third celebrity-boxing pairing has yet to be announced, Fox said.
