Andrew Lloyd Webber has announced the tragic passing of his eldest son, Nick.
The heartbreaking news comes after the famed playwright confirmed earlier this week that Nick - who was just 43 - has been moved into a hospice amid his battle with gastric cancer. He received the devastating diagnosis 18 months ago.
Now, the 75-year-old father has taken to Twitter to announce that Nick passed away on Saturday (March 25).
"I am shattered to have to announce that my beloved elder son Nick died a few hours ago in Basingstoke Hospital," Lloyd Webber wrote. "His whole family is gathered together and we are all totally bereft."
Earlier this week, Lloyd Webber took to Instagram to share that he wouldn't be able to support the cast of Bad Cinderella in person on their opening night in New York City, as he was remaining in England in order to be close to Nick.
In his video, the legendary playwright revealed that Nick had just got over "the worst of this first bout of pneumonia he's got as a result of his cancer". The doting father added that he would "pass on all of the fantastic wishes" from supporters.
Nicholas "Nick" Lloyd Webber followed in his father's footsteps as a talented composer, working on projects such as The Little Prince and his dad's Symphonic Suites.
Following the news of his heartbreaking passing, many stars and fans have taken to social media to pay tribute to the composer and record producer.
