JERSEY Shore's Sammi 'Sweetheart' Giancola has had a baby boy with fiancé Justin May after her struggle with infertility.

The star, 38, broke the news on Instagram, calling the little one her "rainbow miracle baby."

"After this very long journey to get here, words cannot describe how blessed and truly grateful we are," she wrote in the caption.

"Forever living in our baby love bubble until further notice."

The baby's name is Vincent Keith May, and he was born on August 20.

Fans were calling the baby Vinny 3.0, following in the footsteps of the show's Vincent 'Vinny' Guadagnino and Angelina Pivarnick's ex Vinny Tortorella, who was nicknamed Vinny 2.0.
