Law enforcement found no signs of foul play and believe Jackson died of natural causes, the gossip site said.

Jackson, who was an Air Force veteran and had been living in VA housing for a number of years prior to Prince’s death in April 2016, used the money from his inheritance to purchase a home.

"He was so busy on the road because he had so many engagements with his music," added Jackson. "So, he had to travel, all around the world. I always saw him on television, read the magazines, and said, 'There's my brother, Prince.' I was so happy he was making it for himself, I really was."

Prince died on April 21, 2016, at the age of 57 following an accidental overdose of fentanyl, according to the toxicology report. The report also indicated the level of fentanyl in Prince's liver was 450 micrograms per kilogram and notes that liver concentrations greater than 69 micrograms per kilogram "seem to represent overdose or fatal toxicity cases."

Representatives for the Prince estate did not immediately respond to Fox News’ request for comment.
