Brad Pitt's got some problems at home ... because while he was out of the country promoting his new movie, cops say his L.A. pad was hit by burglars.
The Los Angeles Police Department tells TMZ ... officers responded to the actor's home for a reported break-in Wednesday night and cops believe 3 suspects entered the home -- though it's unclear what, if anything, was taken.
Our sources tell us Brad was NOT home at the time of the alleged break-in ... he was overseas in Japan.
