Lindsay Lohan's chances of starting an incarcerated starlet gang just went up in smoke ... because LiLo's fellow famous inmate -- "Pretty Wild" star Alexis Neiers -- just walked out of the Lynwood jail a free woman.
According to jail officials, Neiers -- who was serving a six-month sentence for her part in the Burglar Bunch's heist at Orlando Bloom's house -- was just released after spending less than one month behind bars.
UPDATE: Alexis tells TMZ she is very "humbled," "blessed," and "very grateful for my family right now." She says her plans are "to shower get in my bed and relax with my family. I'm very excited for a good meal."
