Jessica and Ashlee, visited Garrison in Twin Towers Correctional Facility, an L.A. County jail last week. The actor is awaiting sentencing for vehicular manslaughter - a 17-year-old passenger died in a crash that occurred when the actor was driving drunk, on Dec. 2, 2006 - and could get more than six years. "He's doing really good, but it's a scary place. He's a good kid with a great heart who's had a horrible life," says Simpson, a former minister. Garrison, who has admitted to having been a teen thief, has his own cell, we're told. "That's helpful for his physical safety," Simpson said. "He'll be all right" - Reported by Ileane Rudolph
