Late pop singer,
The singer had no living children, and was unmarried at the time of his death.
In the same vein, his parents are both dead, leaving Tyka as his next of kin and in position to get all the money.
The pair had had a strained relationship during her days as an addict when she whored herself to finance the habit. The siblings however reconciled in the years before Prince's death.
After going to rehab in 2003, Tyka, now 55, said of her old life: "I was a single mother and my boys were babies. I sold my body for food, money and pampers. I pawned the car Prince had given me and sold the kids’ TV for drugs."
Before things took a negative turn for her, Tyka had a short-lived music career and even released acclaimed album "Royal Blue" in 1988.
Tyka now stands to take Prince’s estimated £200m wealth plus his £350million music catalogue and any money his estate makes in the wake of his death.
Celebrity lawyer, Dan Streisand however believes it is unlikely a man of Prince’s stature would have neglected to make a will.
He said to Reuters, "Hopefully, Prince executed a trust and indicated his intentions, both with respect to who his trustee would be and how he would want the estate to be disposed of," he said.
Arriving at Prince’s Paisley Park complex on Friday, Tyka told fans who were gathered there: "He loved you back."
She was seen carrying a red rose, supposedly meant for Prince’s body.
