LONDON: Michael Jackson's sister La Toya has opened up about the superstar's children - insisting they are still traumatised by the singer's tragic death.

Jackson's mother Katherine was granted full custody of Prince Michael, 12, Paris, 11, and seven-year-old Prince Michael II aka Blanket, after the superstar passed away in June (09) and the trio moved into her home in Encino, Los Angeles.

La Toya admits it is heart-breaking to watch the youngsters deal with such a devastating loss.

She says, "Paris talks about her father all the time. She writes a lot and wears his shirts every day. They still smell of him and it helps her feel close to him. Her bedroom is covered in posters of Michael and she watches tapes of him all the time.

"Prince just doesn't want to speak about it. He won't even watch the DVDs - he just walks straight past the TV. It's too soon, too touching. I do worry about him very much. And Blanket is just a very sad, shy little boy. He cries - he really does cry. No one can bring his daddy back - and it hurts so much. They all go to therapy and I truly hope Prince especially will be able to open up there."
