Matt Keough is the ex-husband of 'Real Housewives of Orange County' star Jeana Keough, and was a legendary professional baseball player in the 1980s.
Kara made the sad announcement on Instagram, which occurred just weeks after the reality star tragically lost her newborn baby boy, McCoy.
"Daddy, please take care of my son. Teach him the circle changeup and how to find forever friends. You’re on grandpa duty in heaven now. Xoxo, Hammerhead," Kara posted on IG alongside a montage of photos and videos of her father.
