A mob rat who helped the feds get a murder conviction against his close friend, Bonanno crime family boss Vincent “Vinny Gorgeous” Basciano, will be sentenced for his own crimes today.

Dominick Cicale, who has already served several years behind bars, is to appear in Brooklyn federal court where he’ll learn, whether in view of his cooperation, he’ll have to do any more time before going into witness protection.

“Gorgeous’’ is doing a life sentence at Colorado’s “Supermax’’ prison.
