The intimate note was part of a collection of intimate personal items including cassettes and a hairbrush with strands of her hair, which was put up for auction by her former friend Darlene Lutz.
Bidding on the breakup letter, which was written a year before Tupac’s death while he was in prison in 1995, had reached $100,000 (£72,000) in July 2017 when Madonna filed an emergency court order over Gotta Have Rock and Roll’s auction – and it has now finally gone to auction with that starting price.
Madonna won a temporary block on the sale of 22 items in July 2016 – telling a New York City court her celebrity stature “does not obviate my right to maintain my privacy, including with regard to highly personal items”.
Lutz, a breast cancer survivor, will donate a portion of the proceeds breastcancer.org.
Bidding begins online on 17 July.
