Alba Caught in Pap Trap

Jessica Alba couldn't escape from paparazzi yesterday -- she was locked in at two red lights and swarmed by photogs!


The pregnant sourpuss was caught riding shotgun in Beverly Hills, with photogs warning her driver it was illegal to turn right on red at one specific spot as they snapped away.

Their pestering paid off though -- Alba finally gave up a smile for the paps! Amazing!
