The Cranberries lead singer Dolores O'Riordan has died suddenly at the age of 46, her publicist has confirmed.
The Irish musician, originally from Limerick, led the band to international success in the 90s with singles including Linger and Zombie.
A statement from her publicist said: "The lead singer with the Irish band The Cranberries was in London for a short recording session.
"No further details are available at this time."
A Metropolitan Police spokesperson said the police were called to a hotel in Park Lane at 09:05 GMT on Monday, where "a woman in her mid-40s" was pronounced dead at the scene.
The police have confirmed that the death is not being treated as suspicious and said a report was being compiled for the coroner.
Her current band mates in The Cranberries - Noel Hogan, Fergal Lawler, and Mike Hogan - paid tribute to the lead singer on social media.
The message said: "She was an extraordinary talent and we feel very privileged to have been part of her life from 1989."

Her publicist added: "Family members are devastated to hear the news and have requested privacy at this very difficult time."
The parish priest from her home town Friarstown, in Limerick, said her funeral would take place in Ireland.
"Her family are still waiting for more details to come from London about her death," said Ballybricken and Bohermore parish priest Fr James Walton.
"The plan is for her to be buried here at home. When that will be will depend on when her body is released."
The Cranberries shot to international fame with their 1993 debut album Everybody Else Is Doing It, So Why Can't We? and went on to sell over 40 million records worldwide.
In 2017 The Cranberries announced a tour including dates in Europe, the UK, and the US.
However, in May - shortly into the European tour - the group had to cancel the remainder of the European dates as a result of O'Riordan's health issues.
The official Cranberries website cited "medical reasons associated with a back problem" preventing singer Dolores O'Riordan from performing.
But just before Christmas O'Riordan had posted on Facebook saying she was "feeling good" and had done her "first bit of gigging in months", leading fans to believe she would soon be performing again.
O'Riordan tweeted a picture of herself with her cat to fans in early January saying she was "off to Ireland".

O'Riordan split from her husband of 20 years, Don Burton in 2014. She and Burton, who is the former tour manager of Duran Duran, have three children together.
The singer was arrested over an alleged air rage incident in 2014 but was released without charge, after a stewardess was reportedly attacked on a flight from New York to Shannon, County Clare.
O'Riordan was taken to hospital in Limerick after being questioned by police and later discharged.
Two years later, O'Riordan was ordered to pay 6,000 euros (£5,300) to charity for headbutting a police officer after an alleged air rage incident.
She was later diagnosed with bipolar disorder in 2015, which she said explained why she was in a "manic" state on the plane.
In an interview in 2013 she said that she had been abused as a child, which led to her developing an eating disorder, and eventually she suffered a breakdown.
She described her family, especially her children, as her "salvation".
Irish president Michael D Higgins called her death "a big loss", and added O'Riordan's work with The Cranberries "had an immense influence on rock and pop music in Ireland and internationally".
Taoiseach (Irish Prime Minister) Leo Varadkar said she was probably "Limerick's greatest ever rock star", and that her band "captured all of the angst that came with your teenage years".
The Kinks guitarist and singer Dave Davies paid tribute to O'Riordan, saying he was "shocked" and that he had seen her "a couple weeks before Christmas".
He added "she seemed happy and well".

Irish rock band Kodaline were among the first to pay tribute on social media.
Absolutely shocked to hear about the passing of Dolores O'Riordan! @The_Cranberries gave us our first big support when we toured with them around France years ago! Thoughts are with her family and friends— Kodaline (@Kodaline) January 15, 2018
Duran Duran's official Twitter feed posted a message saying the band was "crushed" to hear of the singer's death.
Others to pay tribute include The Late, Late Show presenter, James Corden, who said meeting her when he was 15 years old "made his day".
I once met Delores O’Riordan when I was 15. She was kind and lovely, I got her autograph on my train ticket and it made my day. She had the most amazing voice and presence. So sorry to hear that she’s passed away today x— James Corden (@JKCorden) January 15, 2018
Irish popstar Hozier tweeted recalling O'Riordan's "unforgettable" voice.
My first time hearing Dolores O'Riordan's voice was unforgettable. It threw into question what a voice could sound like in that context of Rock. I'd never heard somebody use their instrument in that way. Shocked and saddened to hear of her passing, thoughts are with her family.— Hozier (@Hozier) January 15, 2018
Jim Corr from Irish band The Corrs tweeted offering his "deepest sympathies" to O'Riordan's family.
My deepest sympathies to the family of Dolores O’Riordan who tragically passed away today. RIP— Jim Corr (@Jimcorrsays) January 15, 2018
A book of condolence will be opened in her home town of Limerick on Tuesday, at the city council's headquarters.
O'Riordan, the youngest of seven children, had written her own songs since she was 12.
She joined the band while still in her teens, after spotting an advert for a female singer for rock band The Cranberry Saw Us.
Later changed to The Cranberries, the band's most successful tracks include Linger (1993), Zombie (1994) - a protest song about bombings that took place in relation to the conflict in Northern Ireland - as well as No Need To Argue (1994) and To the Faithful Departed (1996).
O'Riordan briefly pursued a solo career after the band split in 2003, before The Cranberries reunited in 2009.
