Michael Jackson's children cost £2.75 million (NZ$6.5 million) to care for in one year.
New court papers filed by the late Thriller star's lawyers show the huge sum was spent on Prince, 18, Paris, 16, and 13-year-old Bigi - who was previously known as Blanket, though his real name is Prince Michael II - two years ago, with expenses including £290,000 (NZ$685,229) on a house in Calabasas, California, which is rented for the kids at the cost of £22,000 (NZ$51,982.9) a month.
A total of £48,000 (NZ$113,417.23) in fees for Buckley School was also spent for Prince and Paris, before the latter dropped out, with £19,000 (NZ$44,894.32) also being spent on a separate school for "young performers" according to The Sun newspaper.
Other expenses included chartering a private plane for £90,000, £300,000 on staff at their properties as well as £30,000 on other workers, £600 on Bigi's 11th birthday bash and £274,000 for a trip to Hawaii with Prince and Paris' biological mother, Debbie Rowe.
The children are cared for by the music icon's 85-year-old mother Katherine, whose Hayvenhurst home has been purchased by the estate and renovated for in excess of £380,000.
