Never fall in love at the Jersey Shore….Pint-sized guidette Nicole “Snooki” Polizzi is back on the market after splitting from her “juiced-up” beau, personal trainer Emilio Masella. We hear Snook dumped the bodybuilder she met on Facebook.com earlier this year after growing suspicious that the hunk was cheating and “using her for fame.”

Her fears were bolstered after learning that her Guido spent all day last Tuesday at an audition for the next season of MTV’s The Real World.

Snooki is currently filming season 2 of MTV’s breakout hit Jersey Shore in South Beach Miami.
