Danity Kane called it quits again after an ugly recording studio fight! The three remaining members, Aubrey O'Day, Dawn Richard, and Shannon Bex, decided to part ways. They released an open letter to fans on their website.

"During a recent group meeting, 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," O'Day wrote.

"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."

Bex wrote in her own section, "As for the actions that have brought us to this broken ending, I cannot speak for anyone or explain their internal struggles that prompted this heartbreaking sequence of events. All I know is what I have seen. I did not witness a shouting match, a cat fight or a brawl. I witnessed a single direct punch."

The two concluded in a joint portion, "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 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."

We told you yesterday that Richard and O'Day got into an argument at the recording studio, which quickly turned physical. They announced their comeback at the 2013 MTV Video Music Awards, but two members did not return, Wanita "D. Woods" Woodgett and Aundrea Fimbres.

Can you believe they broke up? Let us know your thoughts in the comments section below.
