It was an emotional week for "Real Housewives of New Jersey" couple Teresa and Joe Giudice.

On Wednesday, Joe Giudice's father, Frank, died after collapsing at Joe and Teresa's home in Towaco, New Jersey, People reported.

Frank Giudice, who passed away at age 63, was very close to his son, his grandchildren and his daughter-in-law, Teresa.

"They're holding it together. Joe and his dad were best friends," a rep for the Giudice family told People Magazine. "It's very hard, and the girls have gone through a lot and continue to go through it. There's a lot of emotion going on."

After Frank died, the Giudice family posted a series of photos in memory of him. Even Teresa and Joe's daughter Gia, 13, tweeted a photo of herself and her grandfather with the caption "strongest man I know."

Teresa Giudice also posted a slew of photos in honor of her father-in-law and tweeted, "We love you Dad Forever in our hearts." She then posted a photo of Frank's 11 granddaughters, who are undoubtedly mourning his death.
