Just as fans got their hopes up for the rebirth of Danity Kane, it appears some old habits die hard. TMZ is reporting that the ladies got into a physical altercation during a recent studio session, and things aren’t looking too good. According to the report:

A Danity Kane recording sesh erupted in violence Monday … and they actually needed a first aid kit.

We’re told bandmates Dawn Richards and Aubrey O’Day got physical during a disagreement at an L.A. studio on Monday, resulting in Dawn slugging Aubrey in the head with a closed fist.

DK’s third member, Shannon Bex, was also there and tried unsuccessfully to break up the fight.

This isn’t the first time DK’s had issues … the original five members disbanded in 2009, with four of them reuniting last year.  Aundrea Fimbres quickly dropped out, leaving the remaining three.

Aubrey filed a battery report.  Cops are investigating.

The members have not publicly addressed the issue, however Aubrey did tweet the following cryptic message!
