Jennifer Lopez always slips back into her old ways--the ones of the diva variety, of course. She went to great lengths to hide from the public yesterday as she filmed her music video in downtown Los Angeles. When her team saw a gathering crowd, they set up sheets and tents to walk her to the set. Not only that, but they shielded her with an umbrella and waved their arms. J. Lo is wrapped in a white dressing gown, but she couldn't hide completely. She stands out amongst all those extras dressed as pimps and prostitutes, that's for sure! More pics after the jump
