A woman named Darcell Gresham Johnston has reportedly come forward claiming to be Prince's half sister. She has filed legal documents saying that she is a beneficiary of the late music icon's multi-million dollar estate.

In the legal document obtained by people.com, Johnston says she is an "interested party" and also consents to the "appointment of Bremer Trust, National Assocation as Special Administrator for the Estate".

According to reports, Johnston and Prince have the same mother — jazz singer Mattie Shaw — but different fathers. However, some members of his family "only learned of Darcell's existence a few days ago".

Prince passed away at the age of 57 in his Paisley Park house in Minnesota last month.
