Alex John Aniston hasn't been photographed publicly since he was a clean-cut 14-year-old at the 2004 Hollywood premiere of his celebrity sister's film "Along Came Polly."
When cameras caught up with him nine years later at the anything-goes Burning Man festival in the Nevada desert, AJ -- as he is known -- looked the polar opposite of his polished older sister. The 24-year-old son of Aniston's father, "Days of Our Lives" star John Aniston, and his second wife, actress Sherry Rooney, was punked out with a mohawk hairstyle, tattoo-covered body and Mad Max-inspired outfit.
Asked for a comment about his sister, AJ told the U.K.'s Daily Mail, "It's been happening since middle school [people asking about Jennifer]. It's been a pain in my ass for years. No comment."
For her part, Jennifer Aniston has said nothing about her younger brother, who described himself to the Daily Mail as a "travelling artist," and has never appeared in public with him.
