It's a heartbreaking weekend for Teresa Giudice.
The Real Housewives of New Jersey star's mother, Antonia Gorga, died on Friday. She was 66.
ET has learned that Antonia, who was also mother to Joe Gorga, was admitted to a local hospital for pneumonia back in December and was never released.
"The family is devastated," a source close to the family tells ET.
Before she was admitted, Antonio celebrated her 66th birthday with her family by her side, as documented via Instagram by Teresa.
"Happy Birthday to my beautiful MAMA!" she captioned one of the pics. "I am the person I am because of you. Love you with all my heart."
