The 26-year-old reality TV star said she wants to stay in shape as much as possible so that she fits into her wedding dress, reported Daily Mirror.
"The wedding is like a month after the baby, which is why I'm doing this fit pregnancy because after you give birth, you can't really work out. You have to recover... And I'm going to need to squeeze into my dress," she said.
Despite her busy schedule and preparing for the new tot's upcoming arrival, Snooki insists she is not worried about her wedding day because she's already got it organised.
The TV star already has 20-month-old son Lorenzo with LaValle.
