Keyshia Cole's Mother -- I Want a Piece of Birdman, Too!

The apple doesn't fall far from the tree ... when we asked Keyshia Cole's mother what she thinks of Birdman ... she was ready to go to blows.

As TMZ first reported, Cole was arrested last week for allegedly attacking a woman partying in Birdman's condo. Cole and Birdman are reportedly dating ... so you get why she was upset -- though the alleged victim claims nothing happened with her and Birdman.

At Cole's album release party Sunday night, Keyshia's mom clicked into Protective Mother mode.
