Nashville, Tennessee - Pop singer Michelle Branch was arrested for domestic assault after allegedly slapping her recently estranged husband.

According to court documents obtained by TMZ, Branch (39) had admitted to police that she had slapped her husband Patrick Carney, drummer for the band The Black Keys, on Thursday "one to two times."

In a mugshot released by the Davidson County Sheriff's Office, the star appears to have a bruise on her face, but according to the outlet Carney appeared uninjured.

The arrest came shortly after it was revealed that the two were in the middle of a messy break-up.

In a now deleted Tweet, Branch accused Carney of cheating on her with his manager Haley McDonald "while I was home with our 6 month old daughter."

She also said, in a statement to TMZ regarding the split, that "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 singer continued.

Bail for the star was set at $1,000 after she was taken into custody, but she has since been released and is back home with her daughter.
