Pia Zadora — who starred with unlikely duo Orson Welles and Ed McMahon in the 1982 movie “Butterfly” — is making a comeback with live show “Pia: Reloaded” at the Metropolitan Room.

Her re-emergence caught the attention of indie rocker (and Lena Dunham’s boyfriend) Jack Antonoff, 30, who tweeted, “There’s nothing in life I would love more than a feud with Pia Zadora.”

Zadora, 60, told us a feud was for the young, but, “There is nothing more I would like than to be 40 again. But I guess I’ll have to settle for a feud with Jack Antonoff. Game on!”
