The Jersey Shore star, who is expecting her first child with fiancé Jionni LaValle, confessed that the thought of telling her dad about the baby made her nervous.
"Oh, I was scared to tell my dad, of course!" Snooki told People.
The 24-year-old, who has said that she finds being pregnant to be "scary", went on to say that her family is now looking forward to the unexpected addition.
"[My dad] is excited now," Snooki said. "I think [my parents] are more excited than we are. I'm their only child and this is going to be their [first] grandchild."
The reality star previously vowed not to drink any alcohol while she is pregnant out of fear that her child will be born "with three legs".
Snooki recently moved out of the Jersey Shore house, where the cast is currently shooting the show's sixth season, out of fear for her public image.
