According to online court records, she was arrested and charged with one count of domestic assault after she told police that Branch had slapped him. Booking records show that she was released from custody.

A representative for Branch didn't reply immediately. The Black Keys were not reachable.

Branch said in a now- deleted message that she had just found out that Carney had cheated on her with his manager while she was home with their baby.

The news of her arrest broke after Branch said in a statement that she and her husband were divorcing.

"To say that I am devastated doesn't even begin to describe how I feel for myself and my family," Branch said. I have to figure out how to move forward after the rug was pulled from under me. Privacy and kindness are what I ask for with small children.

Branch made a name for herself in the early 2000s after releasing her first album. Her single "Everywhere" reached the top of the "Hot 100" list.

She worked with Santana and Jessica Harp and formed a duo group called the Wreckers.

The third studio album Hopeless Romantic was produced by Branch and her boyfriend. They have two children with each other.
