Deena Cortese's Son Just Celebrated A Big Jersey Shore Birthday

Deena Cortese's "everything" -- aka her son CJ with husband Christopher Bruckner -- is officially a member of the single digits club!


The Jersey Shore: Family member Vacation star's bundle of meatball joy celebrated his first birthday this past weekend, and yes it was a special day for little lad and also his family member and friends.


"Last year today at 4:41 PM my life changed .. I was made a mommy and it also was the ideal thing that ever happened to me," Deena captioned the Instagram album above. "I can not believe your One today CJ time is flying .. Saying your my entire world in a under statement .. This has been the ideal year of our lives and most exhilarating watching you do all your firsts and seeing how excited new things make you .. You’ve brought so much love and joy into our entire family member .. You are the most ridiculous and sweet boy and your habitually so happy.. You have a smile that will light up an entire room .. We love you so much our little Christopher John."


Nicole "Snooki" Polizzi, Jenni "JWOWW" Farley and Mike "The Situation" Sorrentino shared matching "second family member snapshots from the bday bash (as seen below).
