The music has stopped (again) for Danity Kane.

The girl group announced Friday that they have broken up a second time following allegations by Aubrey O'Day that she was punched by one of the other members of the group.

The biggest celebrity feuds

O'Day and Shannon Bex released lengthy letters Friday on Danity Kane's official website detailing the decision behind the split. "During a recent group meeting," O'Day wrote, "a business conversation took a turn for the worst when my group member punched me in the back of my head while I was speaking to another associate. To be clear, she was not physically engaged or threatened prior to her attack on me. This is the same information I provided to the police, and witnesses also corroborated this account of the incident. I cannot condone or excuse any form of physical violence, particularly at the hands of someone I considered family. Disagreements happen. But a war of words and ideas should never end in physical aggression."

According to a report by TMZ.com, Dawn Richard was the aggressor in the attack. Shannon Bex discussed "this heartbreaking sequence of events" in a separate letter. "I did not witness a shouting match, a cat fight or a brawl. I witnessed a single direct punch," she wrote.

In a third letter penned by both O'Day and Bex, the two expressed their regret that  Danity Kane's reunion was short-lived. "We know it must be devastating for our fans to have spent the last twelve months supporting our every move, and for that we cannot apologize enough. We share your frustration and anger! We spent a year living on each other's couches, sacrificing any solo opportunity that came our way, finally finished our comeback album, and were days away from filming three music videos for you that would have played out as a short movie. We lived on calls, traded endless e-mails, and sat in meeting after meeting to bring together an amazing team of producers, agents, directors, and styling teams with no manager in place. We were at the finish line.  We wish, more than anything, that our time, our team's time, and most importantly your time as fans, was not taken for granted and carelessly disregarded.  If this ending was in our control, please understand that we would have done everything in our power to move things forward."

Danity Kane first formed in 2005 on the third edition of the MTV reality series Making the Band. O'Day and former member Wanita "D. Woods" Woodgett were removed from the group in 2008 by Bad Boy Records head P. Diddy. The remaining members, including former member Aundrea Fimbres, disbanded the following year. O'Day, Bex, Richard and Fimbres reunited last summer, but Fimbres left in May 2014 to start a family.
