A source confirmed the sad news to People, though details on the death have not yet been announced and Teresa and Joe have not yet commented.
Antonia made many appearances on the Bravo reality series over the years and she was constantly featured on her kids’ social media pages.
“Mommy I love you so much ❤️ #daughtersloveforhermom,” Teresa captioned the below photo on Instagram back in December. Fans have taken to the comment thread of the photo to pay their respects.
We send our thoughts and condolences to all of Antonia‘s loved ones during this difficult time.
