BB King's kids fight over his multi-million dollar estate?

Singer BB King's 11 children are reportedly fighting over the division of his estate.
The blues legend, who died in May last year, aged 89, fathered 15 children from 15 different women during the course of his eventful life, and the surviving 11 are currently fighting with his appointed trustee over his estate, said The Hollywood Reporter.
The children have claimed the estate is worth between USD 30 and USD 40 million, and insist they were each promised a proportion of the fortune in a will the music icon wrote up in 2007.
On the other hand, LaVerne Toney, the executor of his estate and also King's long-time business manager, is said to be following a 2014 trust.

In it, the children are named but they are not given specific monetary gifts. It is claimed, too, that the value of the estate is markedly smaller than the surviving children have suggested, at around USD 5 million.
