Michael Jackson's Mom Shares Personal Memories Of The King Of Pop As A Child (VIDEO)

When Michael Jackson passed away in June 2009, the world didn't just lose a pop icon; a mother lost her son. While Katherine Jackson still experiences the pain of that devastating loss, she also remembers happier times with Michael -- especially private moments from when he was a child growing up in Gary, Indiana.

In this sneak peek from a new episode of "Life with La Toya," Katherine reminisces about Michael's childhood, opening up about his young antics at the Jackson family home in Gary -- a place where she says she can still feel Michael's presence. "I sit in that house sometimes and I can see Michael running around in it," Katherine says.

As a child, Michael was surrounded by eight siblings -- Rebbie, Jackie, Tito, Jermaine, La Toya, Marlon, Randy and Janet -- but when the older children would go to school, Michael had no trouble entertaining himself. "He was just a little thing, [but] he would find those big shoes of Jackie's or somebody's and just walk around in them," Katherine remembers.

Though this type of memory makes Katherine smile, it also brings her tremendous pain. "It just brings tears to my eyes because all the kids are here but him," she says. "It hurts inside."
