Los Angeles: Michael Jackson's kids attended a ceremony at a children's hospital, where they donated some of their late father's art.

The sketches included a picture of Mickey Mouse, one of Peter Pan, and one of his famous moonwalk.

Also in attendance were their grandmother Katherine Jackson, aunt Latoya Jackson and their cousins Jermajesty and Jafaar, according to reports.

"They are pretty happy kids now. Prince and Paris are going back to [private school] this year. They love the social aspect of it," a source said.

"Paris wants to follow her father into show business. She really wants to be an actress. She loved taking acting classes," the source added.

The pop icon died on June 25, 2009 of a suspected cardiac arrest at his Los Angeles home.
