Just a few days after PEOPLE confirmed that Nicole "Snooki" Polizzi is engaged and pregnant
, her fiancé, Jionni LaValle
, took to Twitter to share excitement for their big news.
"Thank You everyone!! Sorry about that wait but glad everyone's happy!!" he wrote on Wednesday afternoon
, referencing the weeks of speculation about their bundle of joy.
"Nicole and I are real excited!! Our baby is going to be #ShortnTan."
LaValle, who began dating the Jersey Shore

"All u jealous, disrespectful haters out there, u see what u wana see on TV!" LaValle tweeted
. "My fiancé and I n JR are going to be so happy! #youllgeturs"
