Another “Jersey Shore” party pal has entered the world of parenthood. Paul “Pauly D” DelVecchio tells TMZ.com “he’s a proud father” of a baby girl. The 33-year-old DJ and MTV reality star says he’s “excited to embark” on this new part of his life. The mom is a woman Pauly D met last year while working as a DJ in Las Vegas. She apparently filed court papers in New Jersey to establish paternity but TMZ says Pauly has taken a DNA test and knows he’s the father.
