Caitlin Fortunato, 18, is spending her summer vacation chasing a dream — to become Mrs. Vinny Guadagnino.

She’s arrived on a mission to get hitched to Vinny, one of the bronze-skinned, thick-haired Guidos who set hearts (and fists) pumping on the hit MTV reality series “Jer sey Shore.”

“I would like to marry him,” the northern Jer sey girl shrieked as she waited outside the cast’s gray-shingled house in Seaside Heights.

“I saw Vinny the other day and I asked him to marry me, but he didn’t hear me. He’s so sexy. He’s a true Guido. He’s not just faking it; it’s from the heart,” said Fortunato, who drove to Seaside Heights for a weekend of stargazing with her college roommates — and maybe to land the man of her dreams.

Sorry, Caitlin, but you have lots of competition.

In big hair and short skirts, they come. Crowds of girls — and a few boys — spend every day outside the “Jersey Shore” house.

Local police patrol the front yard to ward off love- struck fans of The Situation, Vinny, Pauly D, Ronnie, Sammi, Angelina, Jwoww and fan favorite Snooki, who got busted for disorderly conduct last month after a midday beach booze binge.

Aside from combing the streets, obsessed fans troll the crew’s local hangouts — Bamboo Bar, Karma and Bubba’s Dog House.

Vinny, 22, a soft-spoken Guido from Staten Island, caused a frenzy recently when he emerged from the house carrying two bags of laundry. “Oh, my God! Oh, my God! I just saw Vinny,” screeched Kiley Fulton, 15. “He’s doing his laundry. That’s so cute.”

Laura Grzyb, 21, came from Tennessee with Katharina Kraus, 16, an exchange student from Germany who spent her first night in the United States driving up to the Jersey Shore for a look at her favorite US export.

“They wanted to know what I wanted to see, and I said, ‘Could I go [to the Jersey Shore]?’ ” Kraus said. “They all seem so nice. In Germany, this is an important show. All the Germans like them.”

Gladys Porchetta, on a weekend getaway, was determined to meet Pauly D.

“We’re here until Sunday, so we’ll just keep trying our luck,” said the blonde.
