After Michael Jackson's sudden passing, the singer's three children "are doing fine," says Brian Oxman, the Jackson family attorney for 20 years.

"They are in the care of a nanny," he tells Usmagazine.com, adding that they're staying with their grandmother, Katherine. "Ms. Jackson will care for them and I'm sure there will be all kinds of discussions that will take place about the kids."

The children -- Blanket, 7, Paris, 11, and Prince Michael, 12 - are "just beautiful," Oxman says. "They're well-trained, well educated and extraordinarily talented. They get to play with their cousins and their nieces and their nephews. They are just smarter than smart can be."

Adds Oxman, "I know that they are now all together."
