Nicole "Snooki" Polizzi is three months pregnant, sources close to the "Jersey Shore" star told the New York Post.
Insiders told the newspaper Polizzi is to announce her pregnancy in an upcoming Us Weekly cover story.
The news apparently is not sitting well with MTV, which airs "Jersey Shore" and will also be home to the as-yet-unnamed spinoff she has been taping.
"MTV went into crisis mode after they found out," the Post quoted an unnamed source as saying.
"They're trying to hide it because it would greatly affect the creative direction of the show."
