Prince's onetime lover and musical partner Sheila E. is rumored to be desperate to preserve both his music empire and his $300 million fortune.

The sultry performer, who collaborated with the "Purple Rain" singer on numerous projects, is reported to have recently approached his sister about now running his estate.

Tributes Continue to Pour in Dragon

The 57-year-old legend died last week after he was found unresponsive in his Paisley Park mansion. Since then, tributes have poured in from all fronts for the soulful singer.

As for the 58-year-old Sheila E., a source told Radar Online the "Glamorous Life" singer "wants to protect his legacy at all cost."

While family members are reported to be hesitant to the idea, the source added "Prince's friends are lobbying hard for Sheila to be in control."

Presently, a court has granted Prince's sister Tyka Nelson the right to serve as executor of his estate after it was established he had not left a will. His estate also includes an invaluable catalog of all his works.

"There's complete and utter chaos because Tyka isn't well versed in managing anything like this," a source added. "But the other half siblings are even less equipped to deal with it."

The source added Sheila E.'s offer isn't seen as a power-grab or an attempt to get her hands on his fortune and she has even offered to serve at no charge.

Prince Rumored to be Taking Drug Percocet

Meanwhile, investigators are now rumored to have found drugs in the form of prescription painkillers in Prince's possession after recovering his body.

Word is the Minneapolis police department has now solicited the assistance of the federal Drug Enforcement Administration in continuing their investigation.

Reports are Prince regularly used the drug Percocet for pain he was experiencing in his hip, presumably incurred from years of dancing and high hell shoes during countless live performances.
