Adele has split from her husband Simon Konecki after more than seven years together.
In a statement on Friday, her representatives Benny Tarantini and Carl Fysh said: "Adele and her partner have separated.
"They are committed to raising their son together lovingly. As always they ask for privacy. There will be no further comment."
Adele gave birth to her son, Angelo, in 2012. The 30-year-old married Konecki, a charity entrepreneur, in 2016 after five years of dating.
The couple married in secret and Adele first publicly addressed the wedding during an acceptance speech at the 2017 Grammys.
Adele, who is notoriously private, reportedly started dating charity boss Konecki in 2011 and they were first pictured together on holiday in Florida in January 2012.
In June that year, a 24-year-old Adele announced she was expecting her first child, confirming the news on her blog.
She wrote: "I'm delighted to announce that Simon and I are expecting our first child together.
"I wanted you to hear the news direct from me, obviously we're over the moon and very excited but please respect our privacy at this precious time. Yours always, Adele xx."
The couple's son, Angelo was born on October 19 2012. Adele would later describe motherhood as "hard but phenomenal". She added: "It's the greatest thing I ever did."
Adele took a break from performing following the enormous success of her 2011 album 21, and her Oscar win for the theme from James Bond film Skyfall.
The singer denied being a "recluse" and in December 2014 took the rare step of issuing a public statement on her private life.
She dismissed reports she had split from Konecki, writing on Twitter: "Just wanted to wish everyone happy holidays & all the best for 2015! PS Simon & I are still very much together, don't believe what you read x."
Adele and Konecki tied the knot in a secret ceremony in 2016 but thanks to her closely guarded private life, managed to keep the news under wraps.
However, she confirmed she had walked down the aisle while picking up the Grammy for album of the year in February 2017.
During an emotional acceptance speech, she said: "My husband, my son, you're the only reason I do it."
And she removed any doubt over her marital status a month later during a concert in Australia.
While discussing her worldwide hit Someone Like You, which is about a break-up, she said: "Obviously I can't go through with those feelings because I'm married now. I've found my next person."
Tottenham-born Adele released her debut album, 19, in 2008, which contained the songs Chasing Pavements and Hometown Glory and reached number one in the UK.
Her eagerly anticipated follow-up, 2011's 21, brought even more success thanks to the singles Someone Like You, Rolling In The Deep and Rumour Has It.
The record topped the charts in 30 countries, including the US and UK, and cemented Adele's status as one of the world's best-loved artists.
Adele released her most recent album, 25, in 2015, which contained the single Hello. It proved to be another critical and commercial success.
In March, Adele was pictured entering a recording studio in New York City, sparking rumours she was working on new music.
