Michael Jackson’s kids — Prince, Paris and Blanket – made a rare public outing this week and ET's cameras caught them.With two security guards trying to block cameras at every turn, the kids attended a Nickelodeon Kids' Choice Awards GBK gifting lounge with aunt La Toya Jackson to pick up some free swag. Blanket was mostly quiet and keeping to himself; Prince wore dark shades and sucked on a candy stick; while Paris wore a black Michael Jackson T-shirt in tribute to her dad.At one point all four posed for a photo, with Paris holding a Red Cross flag in support of their efforts to help the victims of Japan.
