Dolores O'Riordan's boyfriend, Ole Koretsky, breaks his silence a few days after the singer's death.

A record producer, Koretsky had been working with the Cranberries lead singer and The Smiths' Andy Rourke in a new band called D.A.R.K. before she died. In the group's official statement released through its website, Koretsky said his heart is broken and "beyond repair."

"My friend, partner, and the love of my life is gone," he stated. "Dolores is beautiful. Her art is beautiful. Her family is beautiful. The energy she continues to radiate is undeniable."

Koretsky continued that he is "lost" and that he misses her so much. "I will continue to stumble around this planet for sometime knowing full well there's no real place for me here now," he finished.

O'Riordan was in London to record a cover of her group's hit song "Zombie" with rock band Bad Wolves when she was found "unresponsive" at a hotel in Park Lane on Jan. 15.

While her sudden death remains a mystery, the coroners have earlier declared there was nothing suspicious about it. Still, authorities have done a postmortem investigation, with results set to be out in early April.

A private Requiem Mass for the 46-year-old singer will be held at the Church of St. Ailbe in Ballybricken, Co Limerick, her hometown, on Tuesday. Canon Liam McNamara, a close family friend, will officiate the mass. The private funeral will be reserved strictly for just close family and friends.

However, there will be a public reposal on Sunday, at Limerick's St. Joseph's Church at 12:30 to 4 p.m., GMT.

O'Riordan was the frontman of Irish band Cranberries, which rose to fame in 1993 when its debut album, "Everybody Is Doing It, So Why Can't We," sold over 40 million copies worldwide.

Following her death, music streaming of the band's former hits rose by 2,934%, as compared to the previous days. The top songs, according to Nielsen Music, are "Zombie," "Linger," and "Dreams."
