The reality star is said to be expecting a baby with boyfriend Jionni LaValle, though she has denied the speculation.
Emilio Masella has since expressed hope that reports concerning his ex-lover are not true, claiming that the 24-year-old has always been flippant about pregnancy and motherhood.
"I hope for her sake... not to be rude or anything... but I hope she has a miscarriage," TMZ quotes him as saying.
"I would def recommend her to get a pregnancy test to see who the father is because I'm sure there are other subjects...Vinny [Guadagnino, her Jersey Shore co-star] could easily be the father."
Masella also alleged that Snooki "wanted twins" with him when they were dating and tipped her to "pull a Kim Kardashian" on LaValle, stating: "[She is] going to have the baby and break up with him right after."
Snooki and her Jersey Shore colleague Jenni 'JWoww' Farley are currently readying their own spinoff show.
