Is Snooki pregnant again?

Los Angeles - Snooki is reportedly pregnant again.

The former Jersey Shore star, who has an 18-month-old son, Lorenzo, with her fiancé Jionni LaValle, is expecting their second child later this year, but is desperate to keep the news a secret.

A source told the New York Post's Page Six that the 26-year-old star is already a few months pregnant but doesn't want it to affect her lucrative personal appearances.

A spokesperson for Snooki declined to comment.

Snooki, whose best friend JWoww is also pregnant, previously admitted she was eager to expand her family.

She said: "Right when I get married I want to have my second kid right away. I want like three more. I want like the Brady Bunch. I think it's because I'm an only child and I never really had anyone to play around with so I want a big family."

Earlier this week, the reality TV star - real name Nicole Polizzi - revealed she is planning to have a 'Great Gatsby' themed wedding.

Although she wants her big day to be special, the star is not going to spend a fortune on her wedding and is going to cut costs where she can.

She said: "I don't have a wedding planner. I'm trying to save money - I'm so cheap! Plus, I don't like people telling me what to do."
