The 26-year-old former "Jersey Shore" star announced the news in a lengthy blog post on Friday titled "The Truth About My Pregnancy."

"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!" she wrote.

She also address media rumors about her relationship, reiterating that she and LaValle are very happy together: "He's my best friend and I'm his. We're sorry that some weirdo had to make up a story to sell to try and ruin us, but honey we are very secure in our relationship and I know and trust my man, he wouldn't hurt me or our family. He's a real man. So we will pray for you and hope one day you can find happiness. The wedding is still on as scheduled and it will take the apocalypse to change that."

The couple got engaged in 2012 and already have a 19-month-old son named Lorenzo Dominic. They're expected to tie the knot later this year.
