"Every morning, all through the day, I think about Michael," she said on Monday night's Piers Morgan Tonight. "If I wake up through the night, my mind is there."
When Morgan asked if she'd ever "get over" her son's death, she replied, "Never."
"I just miss him," she added. "But being a Christian and believing in resurrection, I feel that I'll see him again."
She then became teary, apologizing for getting choked up. "I'm sorry," she said. Morgan told her it was "perfectly understandable," and he couldn't "imagine a worse thing" than a parent having to bury his or her own child.
"It's so unnatural, isn't it?" he asked.
"Yes, it is," Katherine, 82, replied.
After Michael passed away, Katherine became the guardian of his three children: Prince, 15; Paris, 14; and Blanket, 9. Katherine Jackson's complete interview with Piers Morgan airs Monday at 9 p.m. on CNN.
