Snooki & Pauly D -- Some A-Hole Nazi Gave Out Our Cell Phone #s

Snooki and Pauly D were forced to change their cell phone numbers yesterday ... after some swastika-loving Nazi jerkwad hacked into JWoww's Twitter account and gave out their digits to all of her followers, TMZ has learned.

Here's what we know ... the Anti-Semitic mystery hacker took over JWoww's page on Sunday night -- changed her Twitter avatar to a swastika -- and then gave out several private numbers to all of JWoww's 3.3 MILLION followers.

Among the released numbers -- Snooki, Pauly D, Deena and Perez Hilton.

We're told the Snooks, Pauly and Deena have already changed their numbers in the wake of the hack -- we're guessing Perez probably followed suit.

JWoww has since regained control of her Twitter page -- and got rid of the Nazi symbol. The identity of the hacker is still unknown.
