Michelle Branch was arrested following an alleged domestic dispute with her husband Patrick Carney, whom she had accused of being unfaithful.
The Davidson County Sheriff's Office confirmed to PEOPLE that Branch, 39, was taken into custody and booked for domestic assault around 2 a.m. Thursday after slapping Carney, 42, across the face at the couple's Nashville home. The singer-songwriter had Tweeted and deleted a note two hours earlier claiming the Black Keys drummer had cheated on her while she was home with their 6-month-old baby.
Branch was released on $1,000 bond and is due in court on Nov. 7. Later Thursday, the "Goodbye to You" singer announced that she and Carney were separating.
"To say that I am totally devastated doesn't even come close to describing how I feel for myself and for my family. The rug has been completely pulled from underneath me and now I must figure out how to move forward," Branch said in a statement to PEOPLE. "With such small children, I ask for privacy and kindness."
A rep for Carney did not immediately respond to PEOPLE's request for comment.

The musicians tied the knot at the Marigny Opera House in New Orleans in April 2019 in front of friends and family including 17-year-old daughter Owen Isabelle from her first marriage and their son Rhys James, 4 this month. They are also parents to daughter Willie Jacquet, who was born in February.
"Welcome to the world, sweet Willie girl ❤️," Branch captioned an announcement on her Instagram account at the time. "She's named after Patrick's grandmother Willie Madge and has my mother's maiden name/my middle name. We're so in love 🥰."

This is the second marriage for Branch and the third for Carney; she split from Teddy Landau in 2014 after 10 years of marriage, while Carney was previously married to Denise Grollmus from 2007 to 2009 and Emily Ward from 2012 to 2016.
The Black Keys are currently touring in support of their eleventh album, Dropout Boogie, which was released in May.
Branch announced last month on Twitter that her first single, "I'm a Man" from her upcoming album The Trouble with Fever, was out. Her album is scheduled to drop Sept. 16.
