'Jersey Shore' Boys -- Fixing Their Speech Impediment

Ronnie and Pauly D from "Jersey Shore" have barely mastered English -- but TMZ has learned they're already trying their hands at Italiano ... all in preparation for their new season abroad.
A rep from Rosetta Stone tells TMZ, they sent their Italian language program to several members of the "Jersey Shore" cast -- and according to a source close to the show ... Ronnie and Pauly have already made impressive progress with the program.
No word on the other cast members' language-learning plans -- except for Deena Cortese ... whose rep tells us, she'd rather spend her time hitting on guys than studying those word thingies.
Me fail English? That's unpossible.
