Call him Uncle Pauly D!
Nicole "Snooki" Polizzi's Jersey Shore costar gushed to PEOPLE about being a part of her newborn son's life.
"That baby is adorable," he says of Lorenzo, who graces the cover of PEOPLE this week. "He already has hair! We are doing a blow out!"
The deejay, who attended MTV's VMA bash Thursday, says the upcoming premiere of his reality show's final season will be "bittersweet."
"I enjoyed doing it," he says of filming in Seaside Heights, N.J., one last time. "I'm excited to show the world that season. It's the last one. So, we went out with a bang."
