It was all big smiles and friendly faces on the red carpet for the 2009 AFI Film Festival premiere of Bad Lieutenant: Port of Call New Orleans, but Jennifer Coolidge revealed to Entertainment Tonight that during filming, she and Eva Mendes were engaged in a pretty intense cat fight.

Of course, the curvaceous funny lady was referring to her fictional tussle in the film with the sultry Latina actress. Coolidge explains, “I was so exhausted after fighting with Eva because she’s really strong, and we had to fight over some drugs in a purse. She tired me out…She has more energy than I have.”

And on another note completely, who the hell stole Melanie Brown‘s pants???
