Selena Gomez Intruder Thrown In Jail For Creeping At Her Home

The guy busted for lurking around Selena Gomez's home is getting a new place of his own -- a jail cell --  after he was convicted today of trespassing on her property ... TMZ has learned.

Juan Garcia pled no contest to creeping around her house.  Garcia was sentenced today ... to 120 days in L.A. County Jail.  Once he's out he's ordered to stay 150 yards away from Selena and her property ... for the next 3 years.

Garcia will be on 3 years probation, but here's the problem.  Talking sense into an obsessed fan or a stalker is a difficult proposition ... even with the threat of jail.
