Björk’s former partner Matthew Barney has reportedly filed a child custody suit against her.

The 49-year-old Army of Me singer shares 12-year-old daughter Isadora with the New York City based multimedia artist.

And according to Page Six, Matthew has accused Björk of hogging their child’s time in a new lawsuit he filed at the Brooklyn Supreme Court.

“[Björk] is effectively sacrificing Doa’s emotional well-being in favour of her own selfish desires,” Matthew’s complaint reportedly reads, in which he refers to Isadora by nickname ‘Doa’. “[Björk’s] self-focused mindset .?.?. flows, in part, from her belief that as Doa’s mother, she has far greater rights than I do as Doa’s father; and, in part, from her insistence that I am solely to blame for the breakdown of our relationship and the end of our intact family.”

Matthew and Björk were together for 13 years before they parted ways in 2013. The messy breakup is addressed throughout her new album Vulnicura, as she memorialises the pain of their split in vivid lyrics.

Björk splits her time between her hometown Reykjavík in Iceland and New York City.

Page Six reports Matthew made it clear in his lawsuit their daughter Isadora spends the fall semester of school in Iceland and attends St. Ann’s School in Brooklyn Heights during the spring in addition to having a live-in tutor support her studies wherever she goes.

But according to him, Isadora wants to spend more time in New York City.

“[Equal time with her mother and father] is something which Doa — an articulate, intelligent 12-year-old girl — has stated, on her own initiative, that she wants,” Matthew argued in court documents.

“As such, the needs and desires of the child are being given lower priority because of [Björk’s] insistence upon having a greater amount of time with the child.”

Both parties declined to comment to Page Six about the alleged child custody conflict.
