Prince's siblings are said to be locked in a bitter feud over his estate after a judge confirmed the music legend left no will. The state of the Purple rain crooner's estate is said to have hit home when his younger sister Tyka Nelson and his brothers Alfred and Omarr attended a meeting in Minnesota.

The 57-year-old musician was found unresponsive in his Paisley Park Minnesota on 21 April, days after he was briefly hospitalised for what was said to be a bad case of flu. At the time of his death, his business affairs are said to have been in a mess because he was distrusting and paranoid that he had been taken advantage of in the past. As a result, Bremer Trust has been enlisted to temporarily oversee his sprawling fortune and musical legacy.

According to TMZ, Nelson, who filed paperwork requesting a Minneapolis court name her special administrator to oversee his estate, stormed out of the family's first meeting after discussions over the division of his assets got heated.

Under Minnesota law, the estates of people who die intestate are passed to their closest relatives. This means that all Princes' six siblings are entitled to an equal share of his possessions - regardless of the degree of their family ties. The site claims that she believes she is entitled to more than them because she is his only surviving full sibling, hence his closest relative.

Nelson has struggled with drug addiction in the past and the mother-of-two previously told a US magazine that she had sold sex to buy Pampers for her baby. She had managed to rebuild her relationship with her brother in recent years after he got her into a rehab and helped her become a better mother to her sons, Sir and President.

Earlier in April, Prince's former manager Owen Husney admitted that he hoped Nelson would not inherit the rights to her brother's multimillion dollar fortune claiming she lacked "business-savvy".

"I'm sure Tyka is a great person," he told the Press Association. "I would be remiss to think she has the music business savvy to be able to handle a body of work that's got to be worth $250m-$500m (£360m-£720m)."

He added: "Prince's music has never really appeared in commercials. God forbid someone gets hold of this thing and it winds up in some toothpaste commercial. I pray that he has left it in good hands with people who know what they're doing."

Meanwhile, the Minneapolis Star-Tribune reports that investigators have launched a criminal probe to determine the source of the prescription pain-killers found at the scene when he was found unresponsive. "Investigative data collected or created by a law enforcement agency in order to prepare a case against a person, whether known or unknown, for the commission of a crime ... are confidential ... while the investigation is active," said a report citing the law by the Carver County Sheriff's Office.
