Michael Jackson's children made a rare public appearance together last night at the launch party for the new Mr. Pink Ginseng Drink. ET caught up with Paris and Prince Michael to find out their current happenings and what brought them out to the event. "To promote healthiness, actually, because it's a very healthy energy drink," Prince Michael, Jackson's eldest child, said jovially when asked why he and his siblings were at the event. "It's for a good cause, so that's why. And I like it."
