Debbie Rowe has not spoken to Michael Jackson's family since his death.

The former nurse - who was married to the 'Thriller' star and is the mother of his two eldest children, Prince Michael, 12, and 11-year-old Paris - has allegedly tried to make contact but has been unable to get through to any of his siblings or parents Joe and Katherine.

Asked whether Debbie had been in contact with the Jackson family, Former Jackson business associate Marc Schaffel said: "There has been outreach, unfortunately, like so many cases, there's so much going on that they just have not been able to make contact. There were several tries, just for the fact of phone numbers that had changed, you know, answering machines that were full. Contact had not been able to happen prior."

However, Debbie may get her chance to speak to the family - including Katherine, who was given temporary custody of the children last week - at a memorial service for the singer at the Staples Center in Los Angeles tomorrow (07.07.09).

Marc confirmed: "Debbie will attend. We just got confirmation from the people who are handling the VIP seats that they do have Debbie's seats and she will be attending."

It has been claimed Debbie is planning to seek custody of Prince Michael and Paris - Michael's mother was appointed their temporary guardian last week - but Schaffel refused to comment on the reports.

He told US TV show 'Good Morning America': "All I can say is the only one that could give an answer to that would be Debbie Rowe's lawyers, and they're the only ones that could make any kind of official statement on that or obviously make any statement regarding that."

Katherine - who was also made temporary guardian of Michael's youngest son, seven-year-old Prince Michael II following the death of the pop legend from a suspected cardiac arrest last month - was due to go back to court for a further hearing today (06.07.09).

However, it has been postponed until July 13, reportedly due to requests from Debbie and Katherine's lawyers.
