Danity Kane's long-rumored in-fighting is reportedly no longer just figurative. TMZ says a physical fight between two members of the girl group broke out at Los Angeles recording studio on Monday. 

The site says police are investigating an alleged altercation after member Aubrey O'Day filed a battery report against her bandmate Dawn Richard.  Sources say Dawn hit Aubrey in the head during an argument, and that group member Shannon Bex was present but unable to break them up.  Apparently the fight turned so ugly that the ladies had to make use of the studio's first aid kit. 

Aubrey, Dawn and Shannon are the only three remaining members in the group, after Aundrea Fimbres dropped out earlier this year.  The four reunited for a new album last year, after the original five - assembled by Diddy on MTV's "Making The Band" - disbanded in 2009.
