Joe and his wife Melissa Gorga, both 37, had honoured the Gorga matriarch by naming their 12-year-old daughter after her grandmother.
Neither Giudice nor the Gorgas have addressed Antonia’s death on social media. Giudice’s last social media was on an Instagram post on March 1, where she showed off her work with the NephCure Kidney International Foundation.
Joe’s last post was an Instagram shout-out to his wife on Valentine’s Day, while Melissa posted a selfie with her son yesterday.
The siblings recently united their families for a Christmas Eve celebration — the first Giudice’s had at home since her husband of 17 years, Joe, began his 41-month sentence for bankruptcy fraud at the Federal Correctional Institution in Fort Dix, New Jersey.
