Lonnie Short is sitting in jail right now after allegedly stalking Lindsay Lohan. The actress called the Venice, Calif., police after he showed up at her front door.

After a strange, unidentified man showed up and knocked on the door looking for her at 6:30 p.m. last night, LiLo understandably freaked the hell out.

Lindsay, 25, came to the door and asked what Short, 64, wanted. The man responded cryptically that he needed to speak with her. Lohan called for help.

After Lindsay asked the man to leave, he refused, demanding she open the door. Police received a call minutes later about a trespasser on Lindsay's property.

According to law enforcement sources, officials showed up soon after and arrested the man for trespassing. Lonnie Short was booked shortly thereafter.

He's being held on $1,000 bail, and hopefully won't go near LiLo again. Just check out Lindsay Lohan Playboy photos instead, man. No need to bother her.
