The Jersey Shore star - real name Nicole Polizzi - announced her and fiancé Jionni LaValle's happy news via her official website on Friday (4 April)
Snooki wrote: "Jionni and I are so excited to confirm that we are expecting our second child! Now knowing that our test results are good and our baby is healthy, we can finally talk about it!"
Snooki and Jionni are already parents to adorable son Lorenzo, born in August 2012.
Unfortunately for the bubbly reality star, her happy news has been tinged with sadness as she claims friends she trusted let her pregnancy become public knowledge before she was ready.
Snooki wrote a lengthy post on her official website denouncing the people who had reportedly betrayed her trust, saying: "It's not that we want to keep it a secret, but we want to share our business at the right time. We want to make sure our testing is good and when we feel, as parents, is right to say we are expecting, that's when we do so!"
The feisty brunette also slammed recent speculation about her second pregnancy, including the idea that she'd been trying to hide it so as not to jeopardise work opportunities or, even worse, that she'd wanted to take the shine away from pregnant best friend Jenni 'Jwoww' Farley.
Jwoww, another former Jersey Shore star, announced her pregnancy on Christmas Day.
"Are you out of your minds? If you knew Jenni & I personally, you would know we always wanted to be pregnant together. I love Jenni like my big sister, she is everything to me, not fame," wrote Snooki.
"We have a true friendship that I will cherish forever, and getting pregnant just to outshine my best friend is absolutely absurd and disgusting."
Snooki also took the opportunity to tell fans that she and Jionni will be moving into their dream house soon, marrying in autumn this year and that they are very happy together – despite what might have been claimed recently.
"We planned to have a second child before our wedding, and will indeed still be getting married in the fall of 2014. We are a committed family that will raise our children to be the best they can be and give them the best life we can give them. So please, enough with the rude marriage comments," she said.
Congratulations to Snooki and Jionni!
