Editors at the New York Post report the Little Secrets hitmaker, who has often spoken of his battle with substance abuse and bipolar disorder, has begun legal proceedings which are being contested by Mucci so could lead to a complex and drawn out process, including a court trial.

In an interview with Pitchfork.com, Angelakos revealed how in 2011 Mucci had foiled a suicide attempt, saying, "I attempted to jump out the window of our apartment, and she tackled me to the floor. I was paranoid, I thought my career was over."

The singer later dedicated a song on the band's album Kindred to his wife for helping him through his problems.
