Adele has filed for divorce from her husband Simon Konecki, according to legal documents filed in the US.
The singer, 31, announced in April that she and Konecki, a charity entrepreneur, were separating after three years of marriage.
Court documents lodged in Los Angeles on Thursday revealed that Adele has now filed for divorce.
Adele and Konecki began dating in 2011 and had a son, Angelo, in 2012.
Confirming the couple's split in April, Adele's representative said they were "committed to raising their son together lovingly".
The pair tied the knot in a private 2016 ceremony, with Adele publicly addressing the wedding for the first time during an acceptance speech at the 2017 Grammys.
In her speech, she said: "Grammys, I appreciate it. The Academy, I love you. My manager, my husband and my son, you're the only reason I do it."
Tottenham-born Adele released her debut album, 19, in 2008, which contained hit songs Chasing Pavements and Hometown Glory and reached number one in the UK.
Her eagerly anticipated follow-up, 21, brought even more success in 2011 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.
She released her most recent album 25 in 2015, which contained the single Hello and proved to be another critical and commercial success.
Recent reports suggest Adele is recording new music after she was pictured entering a recording studio in New York City in March.
Konecki, 45, reportedly left his job at Lehman Brothers in 2005 and founded the ethical water company Life Water.
In a 2012 interview with Management Today, Konecki said he had been "doing well and earning a lot of money" as an investment banker but "got sick of that greedy and corrupted world".
