Cameron Diaz & Benji -- Kiss Cam Makeout Session ... At Lakers Game

Finally, a highlight at the Lakers game.

For some reason, Cameron Diaz and Benji Madden decided to hit up Staples Center in L.A. Tuesday night to watch the Kobe-less Lakers go down in flames to the Washington Wizards.

But during a break in the action, the newlyweds (married just 3 weeks ago) were put on the "Kiss Cam" ... and they came through strong with some PDA as several fans clapped and cheered.
