Michelle Branch was arrested for allegedly slapping her estranged husband, Patrick Carney, in the face … this in the wake of her claim he cheated on her.

According to docs out of Nashville, obtained by TMZ, on Thursday at around 2 AM police were called to their home for a possible domestic disturbance. Michelle admitted she had slapped Patrick in the face “one to two times,” according to court docs.

Patrick did not have any visible injuries and Michelle was taken into custody. Her bail was set at $1,000 … and it appears she was released from custody early because she’s breastfeeding the couple’s 6-month-old.

TMZ broke the story, Branch and Carney are splitting after 3 years of marriage. She told us Thursday, “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. With such small children, I ask for privacy and kindness.”

The split announcement came just hours after Michelle tweeted accusing Carney of cheating.

Michelle was previously married to Teddy Landau from 2004 to 2015, but married Carney in 2019.
