Michael Jackson's long-time dermatologist does not plan to petition for a role in the upbringing of the singer's three children, his attorney said Thursday.

Mark Vincent Kaplan said Dr Arnold Klein is satisfied that a judge appointed an attorney to oversee the interests of the singer's children, who range in ages from seven to 12.

"It's just not necessary," Kaplan said. "It's already been addressed."

Kaplan said Klein got involved because he was concerned about the children, Prince Michael, Paris Michael and Prince Michael II, having a normal upbringing not related to show business. Jackson told Klein repeatedly that he wanted his children to have a formal education and not be subjected to the rigours of travelling and performing, Kaplan said.

Kaplan surprised many by saying Klein wanted a role in the children's lives during a court hearing earlier this month. A judge ruled that Klein didn't have legal standing to intervene but told the doctor he could file a motion later if he still had concerns.

permanent guardianship

Jackson's mother, Katherine Jackson, was granted permanent guardianship of the children during the hearing as spelled out in the singer's 2002 will.

Klein's involvement in the case raised questions about whether the doctor could be the father of Jackson's two oldest children, a rumour fuelled by tabloid reports and Klein's own cryptic answers when questioned on the matter. Kaplan said during the hearing and on Thursday that Klein legally isn't the father and that questions about whether he is the children's biological father aren't important.

"Whether he is or is not the DNA source wouldn't change one iota greater or less his concern and care about the children," Kaplan said.
