Kara Keough Bosworth is now mourning the loss of her father less than a month after her son died.

Bosworth's father, Matt, has died at the age of 64, nearly 4 weeks after the former reality star's newborn son died during birth.

Bosworth shared the news on Instagram on Saturday, posting several photos of her late dad.

Furthermore, Bosworth added: "You’re on grandpa duty in heaven now."

Bosworth's son, McCoy, died during childbirth on April 6 after experiencing "shoulder dystocia and a compressed umbilical cord," according to an Instagram post.

Bosworth's brother Shane Keough also posted about the sad news of their father's passing, sharing a handful of throwback photos of his father, including one of himself as a youngster sitting on his father's shoulders.

"My favorite place was always on your shoulders," wrote Keough. "It makes me smile knowing McCoy will be there with you; right there on your shoulders."

"It wasn’t always perfect but I wouldn’t change it for the world," Keough continued. "You taught me more than you’ll ever know and I hope that I make you proud. Kick back and enjoy the eternal sunshine. Till I see you again - I love dad."
