"I want to thank everyone for their congratulations and we can feel how excited you are for us!" she added in her post. "We could not be happier! Big things are happening this year with the wedding, moving into our dream house and having our second bambino or bambina!"

Snooki added in her blog post that she wanted to clear the air and still feels "misunderstood" about her relationship with her family and why she's kept the pregnancy under wraps.

"Jionni and I are VERY happy together. He's my best friend and I'm his," she said. "Jionni and I wanted to clear the air by saying we only kept our second pregnancy to ourselves for the health of our child and until we reached a reasonable time to let the world know."

Polizzi and Jionni were engaged in March 2012 and Lorenzo was born later that year in September. US Weekly was the first to report the pregnancy news at the time.
