Lady Gaga Can't Charm a Cop ... She Got Wrote Up!!! (VIDEO)

Lady Gaga is popular with just about everyone ... except cops, because she got nailed in WeHo.

Gaga was at Lisa Vanderpump's restaurant Pump on Santa Monica Blvd. Friday around 11 PM.  It took a long time for her to wade through the crowd ... just long enough for an L.A. County Sheriff's deputy to write her driver up.

The nature of the ticket is unclear, but we think the Rolls was parking in a drop-off area and it was there too long.

The cop's clearly a Katy Perry fan.
