Teresa Giudice is trying to cope with her family's loss the best she can. Two days after the sudden death of her father-in-law Frank, husband Joe Giudice's father, the Real Housewives of New Jersey star thanked her fans for their support and posted family pictures via Instagram.

"Thank you all for your prayers…xx" Giudice, 42, tweeted on June 19. On Friday, she shared several photos of Frank with Joe and the couple's four daughters: Gia, 13, Gabriella, 10, Milania, 9, and Audriana, 5.

"I took this photo of Joe and my Fatherinlaw on Father's Day. We Love you Dad Forever in our [hearts]," she wrote, along with a picture of the father and son. In a second one, Frank smiled on with several of his relatives. "This was also taken on Father's Day. I miss my Fatherinlaw," Giudice added.

Gia also took to Twitter about her grandfather. "Strongest man I know..I love you nonno rest in peace."

As previously reported, Frank unexpectedly died at the age of 63 on June 18. "Joe and his dad were chasing the dog Simba and suddenly Franco fell ill," Teresa and Joe's crisis manager Wendy Feldman told Us in a statement. Noting that they are focusing on "their family right now, especially the girls." Teresa and Joe's sentencing date for their legal woes—originally set for July 8 in Newark—has since been postponed so the family can grieve.
