Kara Keough shared devastating news on Tuesday that no parent ever wants to endure -- her newborn son died.

"On April 6th, our son McCoy Casey Bosworth was born at 3:10am. Weighing in at 11 pounds and 4 ounces and spanning 21 inches, McCoy surprised us all with his size and strength (and overall perfection)," the “Real Housewives of Orange County” alum began on Instagram.
