Pauly D Baby Mama Drama, Name Revealed [PHOTOS]: 'Jersey Shore' Star Fathers Las Vegas Love Child Amabella, Fights for Custody with One Night Stand Amanda

"Jersey Shore" party boy DJ Pauly D just found out that he is the father of a young baby girl named Amabella. The only problem is, Pauly and Amabella's mother Amanda don't get along very well... No big surprise there - they only met and hooked up in Las Vegas once!

As Mstars previously reported:

DJ Pauly D recently admitted to TMZ that he hooked-up with a 26-year-old New Jersey native while partying in Las Vegas last year... and now he as a baby daughter!

Wonder if fellow MTV cast member Vinny Guadagnino will be named the Godfather? Or more importantly... will Pauly's newfound fatherhood affect his bromance with the Staten Island mama's boy?

Anyway, the kid's only a few months old and currently living with her mom in Atlantic City. The unidentifed woman recently filed court documents in Jersey to formally establish paternity. However, Pauly D already took a DNA test, and he's definitely the dad.

Pauly tells TMZ, "I'm proud I'm a father. I am excited to embark on this new part of my life."

InTouch magazine recently found out that the little girl's name is Amabella. It apparently means "lovable" in French. Check out the FIRST photo of five-month-old Amabella obtained by TMZ. How cute! And look at that hair... daddy must be so proud.

But things aren't all good for the new fam... because according to TMZ, Pauly and this one-night stand Amanda "hate" each other.

The new parents are apparently fighting over custody and cash. Sources tell TMZ that Pauly doesn't think Amanda is a "fit" mother because she "once worked at Hooters" and she already has another kid (for someone so young).

Pauly wants some sort of custody, although he hasn't seen the baby (who was born back in May) at all.

Amanda wants child support, and Pauly's allegedly cool with that... but he feels like Amabella's mom is trying to "use" him for his MTV stardom (just check out this baby picture).
