A friend of the couple has disclosed to Us Magazine that Gonis did not accompany Auerbach to the Grammy Awards on Sunday (February 10) due to marriage troubles.
"Dan's wife wasn't there [at the ceremony] because they are going through a divorce," the source told the publication.
Speculation about Auerbach's marriage arose when the vocalist was spotted walking the Grammy Awards red carpet without his wedding ring.
The couple have a young daughter named Sadie Little Auerbach, who was born in 2008.
A spokesperson for the band declined to comment on this latest news.
The Black Keys were victorious at Sunday's Grammys by winning the 'Best Rock Album' category for El Camino.
They beat out Coldplay's Mylo Xyloto, Muse's The 2nd Law, Bruce Springsteen and the E Street Band's Wrecking Ball and Jack White's Blunderbuss.
