Michael Jackson's ex-wife Debbie Rowe will attend the singer's memorial service, it has been confirmed.

The 47-year-old was married to the Thriller star between 1996 and 1999, and is the mother of his two eldest children.

She gave up her parental rights when they divorced.

"Debbie will attend, said Marc Schaffel, described as a former Jackson business associate, on ABC's Good Morning America Monday.

"We just got confirmation last night from the people who are handling the VIP seats that they do have Debbie's seats and she will be attending," Marc Schaffel, a former Jackson business associate, said on ABC's Good Morning America Monday.

Despite her VIP presence at the memorial, Debbie has not been in contact with the Jackson family following Michael's death on June 25, according to Schaffel.

He 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."

Schaffel refused to comment on reports that Debbie is planning to launch a legal bid for custody of her children, Prince Michael, 12, and Paris Michael, 11.

"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," he said.
