Dan Auerbach has reportedly split up with his wife.

The Black Keys guitarist wasn't accompanied by his spouse Stephanie Gonis at the Grammy Awards in Los Angeles on Sunday and sources close to the pair claim they have parted ways.

A source told Us Weekly: "Dan's wife wasn't there [at the ceremony] because they are going through a divorce. The split is unfortunate."

Auerbach, 33, - who has a four-year-old daughter Sadie Little with Gonis - also walked the red carpet without his wedding band.

New Yorker critic Sasha Frere-Jones reprimanded Auerbach for appearing sullen and sour throughout the Grammy broadcast.

Auerbach's split with his wife comes just months after the band's drummer Patrick Carney married Emily Ward.

The couple tied the knot in the backyard of their home in Nashville in September in front of 350 friends and family and the couple's Irish wolfhound Charlotte.

The ceremony was officiated by comedian Will Forte while Auerbach also attended.

The bride wore a lace gown by Carolina Herrera as she walked down the aisle to to Tommy James & the Shondells' Crimson and Clover while the groom opted for a white tuxedo jacket and black trousers.
