Andrew Lloyd Webber announced his son Nicholas has died at the age of 43 after an 18-month battle with gastric cancer.

The 75-year-old Broadway legend revealed his oldest son died in a statement he shared to Twitter Saturday.

"I am shattered to have to announce that my beloved elder son Nick died a few hours ago in Basingstoke Hospital. His whole family is gathered together and we are all totally bereft," he wrote.

Fox News Digital has reached out to Webber's representatives for additional comment.

ANDREW LLOYD WEBBER'S SON ‘HOSPITALIZED’ AND ‘CRITICALLY ILL’ FIGHTING GASTRIC CANCER

Webber shared Nicholas with ex-wife Sarah Hugill, to whom he was married from 1971 to 1983. Webber and Hugill also have a daughter, Imogen Lloyd Webber, 45.

Last Sunday, Webber revealed Nicholas was "critically ill" with gastric cancer and had been hospitalized after battling the disease 18 months.

"I am absolutely devastated to say that my eldest son Nick is critically ill," Webber said in a statement that his representatives shared with Fox News Digital March 19.

"As my friends and family know, he has been fighting gastric cancer for the last 18 months, and Nick is now hospitalized.

"I therefore have not been able to attend the recent previews of 'Bad Cinderella' and, as things stand, I will not be able to cheer on its wonderful cast, crew and orchestra on opening night this Thursday.

"We are all praying that Nick will turn the corner," Webber added. "He is bravely fighting with his indomitable humor, but, at the moment, my place is with him and the family."

Webber's latest Broadway production is a reimagining of "Cinderella," which ran in London's West End from 2021-2022. 

On Thursday, the famed composer posted a video to Instagram in which he shared that Nicholas had been moved into hospice care after being diagnosed with pneumonia during his cancer battle. Webber also expressed his gratitude to his fans for their support and sent well wishes to the cast of "Bad Cinderella" on their opening night.

"Hi, it's Andrew and I want to thank you first for the huge outpouring of messages of support for my son, Nick," Webber said in the clip. "He’s now been moved into a hospice, and he’s battling away. I think he’s over the worst of this first bout of pneumonia that he’s got as a result of his cancer, which is just ghastly. We’re all here, and the family here has gathered around, and it was the right place for us all to be I think."

The six-time Tony Award winner said he was "absolutely gutted" that he had to miss the opening night of "Bad Cinderella" but said "my place is really here in England at the moment."

No other details about the form of Nicholas' cancer have been disclosed, though gastric cancer is more commonly known as stomach cancer.

Born July 2, 1979, Nicholas followed in his father's footsteps and became an acclaimed composer. He earned accolades for his work on the 2017 BBC Drama, "Love, Lies and Records." Nicholas also scored the 2017 musical "Fat Friends" and was the composer on the 2021 U.K. film "The Last Bus." 

Nicholas earned a best musical theater album Grammy nomination as a co-producer along with his father, Greg Wells and David Zippel for the 2021 original cast recording of "Cinderella." The West End musical is now being staged under the name "Bad Cinderella" in New York City.

In 2018, Nicoholas married viola player Polly Wiltshire, who performed in the 2019 movie adaptation of Webber's musical "Cats."

The Los Angeles Police Protective League filed a lawsuit Friday on behalf of three officers against an anti-police website that they claim put a "bounty" on the officers’ heads after posting photos and other personal information on city cops released in a public records request, according to a report. 

The recent release of more than 9,300 LAPD officers’ information has caused a furor within the department after it was requested by police abolitionist group called Stop LAPD Spying Coalition. It also mistakenly included the names of undercover officers. 

"I deeply regret that this mistake happened," Police Chief Michel Moore told FOX 11 last week. "I understand personally, given my own death threats and on matters of me as a public figure and my family has endured as a chief and even before that, how troubling this can be to a member of this organization, and even more so to those that are involved in sensitive and or confidential investigations." 

He added, "We have people who have taken the list and are now criminally, we believe, making threats against the safety of officers, calling for a bounty and awarding a bounty for individuals who would go out and kill a cop."

LAPD CHIEF ACCUSED OF FEEDING PERSONAL DATA TO ANTI-POLICE: ‘BOUNTY ON OUR OFFICERS’

Officers Adam Gross, Adrian Rodriguez and Douglas Panameno, none of whom are undercover, have named Steven Sutcliffe, owner of killercop.com, in the lawsuit, requesting that the photos be removed from the website, according to the Los Angeles Times. 

This is the first litigation connected to the release, the newspaper reported. 

Sutcliffe also has a Twitter handle @killercop1984, according to the lawsuit, on which he allegedly posted on March 20, "Remember, #Rewards are double all year for #detectives and #female cops," alongside an image quoting the General Counsel at Los Angeles Police Protective League saying killercop.com was offering $1,000 and $2,000 to anyone who killed an officer, according to court documents, the Times reported. 

The same Twitter handle linked to a database of the officers’ headshots in another tweet writing, "Clean head-shots on these #LAPD officers. A to Z."

"The posts, the nature of the posts, they’re not just intimidation," Moore said, according to the New York Post. "They’re threatening, and they may constitute a crime. This is one of those things that I worried about and feared when we released these photographs ostensibly to be transparent, that others were going to use them to threaten our officers."

LAPD Detective Jamie McBride called the release of the information "reckless" in an interview with FOX 11.

"I've been notified by a few officers already saying that they're looking at other departments now before they get too much time invested here with the Los Angeles Police Department because they don't feel that this department has their best interests at heart," he said, adding that the Los Angeles Police Protective League has filed a complaint against Moore.

Moore told FOX 11, "We've invited the FBI, as well as the district attorney, and we're going to pursue people who have taken information that was released, some of it in regards that it shouldn't have been released. But they're calling right now for these acts of violence are not against individuals that are in any sense of assignments. They're just calling it out against any officer's photograph at all."

Sutcliffe told the Post his "free speech" was being infringed upon with the lawsuit. 

"It’s malicious. It’s retaliatory. It is vindictive and frivolous. Their motion is filled with lies," he claimed. 

Sutcliffe and Moore for comment did not immediately respond to Fox News Digital.
