Jessica Alba doesn't smile for just anyone -- but this morning the actress brushed the dust off her pearly whites during a traffic stop in L.A. ... and was not-so-shockingly let go with just a warning.
Law enforcement sources tell TMZ Alba was pulled over for speeding this AM in Beverly Hills -- and during the stop, we're told Alba blamed her lead foot on the nearby paparazzi.
We're told Alba -- who was extremely cooperative and smiley during the stop -- was eventually let go with only a warning ... but was told that pap-avoiding is no reason to break the law.
