Michael Jackson’s three children are reportedly under extra security.

Paris, Prince and Blanket have not spoken to their grandmother and guardian Katherine Jackson in over a week.

And following a failed attempt to allegedly remove them from their California home by some of the late singer’s siblings, they are now said to be under heavier protection.

Katherine’s nephew Trent wants the kids surrounded by more bodyguards when they leave the home and Jermaine, Randy and Janet Jackson barred from the property.

“[Trent] is very concerned that an elaborate kidnap could be planned,” a source told RadarOnline.

Meanwhile, it is reported that Randy and Jermaine asked the Michael Jackson Estate to pay for their child support.

The two brothers were both married at one stage to Alejandra Genevieve Oaziaza and each have two children with her.

“Both Randy and Jermaine were behind on their child support payments – the only way they felt they could pay it was through Michael’s estate,” an insider shared.

“Jermaine’s kids Jaafar and Jermajesty and Randy’s sons Donte and Randy Jr. were moved into a condo owned by the estate to help with the legal fees a few years back.”

Randy and Jermaine apparently pleaded for extra help from the estate’s lawyer but their request was “shot down immediately.”
