MICHAEL Jackson's 3 "The next Generation

On Tuesday, at Jackson's Staples Center memorial, attended by a crowd of 20,000, his children sat in the front row with their grandparents, Joe and Katherine Jackson.

His children - sons Prince Michael, 12; Prince Michael II, seven; and daughter Paris Michael Katherine, 11 - have remained in the shadows for most of their young lives, surfacing only in recent paparazzi photos.

But they have come into the spotlight since Jackson's death on June 25.

At the memorial, the three children joined star guests in singing Heal The World.
