‘Brasco’ wed wait

A Gambino gangster who recently got engaged to the granddaughter of a key figure in the famed “Donnie Brasco” case pleaded guilty yesterday to drug charges.

Joseph “Joe Boy” Sclafani’s conviction will almost surely leave his fiancée, “Mob Wives” princess Ramona Rizzo, alone at the altar for the lavish June wedding she’s been planning.

Rizzo is the granddaughter of late Bonanno wiseguy Benjamin “Lefty Guns” Ruggiero, who unwittingly helped an undercover FBI agent named Joe Pistone infiltrate the mob.

Al Pacino portrayed Ruggiero and Johnny Depp played Pistone in the 1997 movie based on the undercover operation.

Sclafani, 47, faces at least 14 years in the slammer under terms of his Brooklyn federal-court plea deal.
