There’s already been one claim that legendary singer Prince had a love child — and his estate anticipates there will be more. In anticipation of those allegations, Prince’s estate has ordered his blood to be analyzed, Minneapolis TV reporter Paul Blume tweeted Friday.

“BREAKING: #Prince estate judge orders genetic testing,” Blume wrote to his nearly 5,000 followers. “Wants #Prince blood analyzed as they anticipate claims of fatherhood for his $$$.”

Prince left an estimated fortune of $300 million, and his estate is expected to grow as sales from his music continue to rise. Since he died without a will, his estate will be split among his sister and half-siblings. A probate hearing Monday determined that Bremer Trust will work on behalf of the heirs.

The “Purple Rain” star’s cause of death is still unknown. But as drug rumors continue, the DEA and U.S. Attorney's Office announced they would join the Carver County Sheriff’s Office investigation. “The DEA and U.S. Attorney’s Office are able to augment this local investigation with federal resources and expertise about prescription drug diversion,” the statement said Wednesday. “While this remains an ongoing investigation, we will have no further comment.”

There are claims that Percocet was found in Prince’s system, but the Midwest Medical Examiner’s Office has not confirmed them. “Midwest Medical Examiner’s Office has not released any information regarding the Prince Rogers Nelson investigation to anyone, including law enforcement,” the office said in a statement Thursday. “Results are pending. This is an ongoing investigation in partnership with the Carver County Sheriff’s Office. We will have no further comment at this time.”

Prince died April 21 at the age of 57 in his Paisley Park home in Chanhassen, Minnesota. He was mourned in a public ceremony at Los Angeles City Hall Friday.
