Snooki says son Lorenzo is getting “smarter and wiser every single day”.

The former Jersey Shore star’s little boy, her first child with fiancé Jionni LaValle, marked his second birthday on Tuesday.

And Snooki honoured the big day by posting a touching blog post paying tribute to her first born.

“Just want to tell the world how proud I am of my son turning two today,” Snooki wrote. “Not only does he get smarter and wiser every single day, but he makes mommy’s love for him grow and grow more each and every minute.

“So sad to know Lorenzo isn’t my ‘baby’ anymore, but he will always be my baby and my first born. I know he’s going to be such an awesome big brother to his sister that he will meet very soon!

“Lorenzo, I love you more each second that I’m with you and I hope one day you will feel that love for me. MOMMY IS SO PROUD OF YOU, happy birthday my handsome son!”

Snooki, 26, later posted a picture of Lorenzo wearing a ‘Birthday Boy’ cape.

The reality star’s pal Jenni ‘JWoww’ Farley also paid tribute to the adorable little boy on her Twitter page.

“Happy birthday to my godson Lorenzo!!! Can’t wait to spoil you!!!” JWoww tweeted.

JWoww also posted a picture of herself with Lorenzo, writing: “Remember holding you in the hospital and thinking to myself how lucky I am to call you my godson. Happy birthday to my godson Lorenzo!!! I love you.”

Snooki is now expecting her second child, a little girl, with Jionni.
