Adele is separated from her husband Simon Konecki, the representatives of the singer have confirmed.
In a statement on Friday, the couple said "committed to lovingly raise their son".
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 best-selling London-born artist is known for her album-top albums 19, 21 and 25.
The statement added that the couple asked for privacy and there would be no further comment.
They married in secret, and Adele first took up the wedding publicly during an acceptance speech at the 2017 Grammys, where she thanked her "husband".

Her third album, 25, sold a record breaking 800,000 copies in her first week and became the best-selling album from 2015.
