The rivalry between Kobe Bryant and Stephen Jackson appears to still be rather heated.

The Lakers and Warriors faced off in a preseason game on Tuesday night.

Jackson lashed out at Bryant after a previous exhibition contest, accusing Kobe of playing dirty. Even though Bryant insisted he didn't read any of Jackson's comments, he attacked the Warriors forward early and with emotion on Tuesday night.

Lakers teammate Ron Artest says any little thing will motivate Bryant.

"He always finds a reason," Artest told the Press-Enterprise. " 'You looked at me the wrong way. Alright I'm giving you 40. You don't want to say my last name. Alright I'm giving you 40.' He's unbelievable."
