Court documents filed in Los Angeles on Thursday reveal Adele has now filed for divorce.
The couple began dating in 2011 and welcomed their son, Angelo, in 2012.
They tied the knot in a secret 2016 ceremony, with Adele publicly addressing the wedding for the first time the following year during an acceptance speech at the Grammys.
After their separation had been confirmed earlier this year, a representative for the British singer said: “They are committed to raising their son together lovingly. As always they ask for privacy. There will be no further comment.”
Posting on Instagram after celebrating her 31st birthday, the singer said that she had “changed drastically in the last couple years”, joking she would be recording a drum and bass record to “spite” the difficult 12 months she’s had.
“This is 31… thank fucking god,” she wrote. “30 tried me so hard but I’m owning it and trying my hardest to lean in to it all.
“No matter how long we’re here for life is constant and complicated at times.
“I’ve changed drastically in the last couple years and I’m still changing and that’s okay.”
She continued: “31 is going to be a big ol’ year and I’m going to spend it all on myself. For the first time in a decade I’m ready to feel the world around me and look up for once.
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.

Let's be honest, break-ups can be messy, particularly in the glare of the spotlight, so it's good to see when two celebrities can put their differences aside and still be friends, as Cameron and Justin did - even eventually going on to star in 'Bad Teacher' together.

And speaking of how to flawlessly handle a break-up...The media coverage surrounding Jennifer Aniston for the decade after her split from Brad Pitt, was often unnecessary, cruel and steeped in sexism. Through it all, though, she kept her head high, kept on working and, more importantly, smiling away, despite what was said about her in the press.Now she's one of the five highest-paid actresses in the world, and recently married her long-time partner, Justin Theroux.
