A pre-Friends Jennifer Aniston, now 45, starred as Jeannie on the Ferris Bueller's Day Off-inspired show, while Charlie Shlatter played the title role. Nelson says the two had a "brief, torrid romance" during the series' 13-episode run.
"GQ can exclusively report that everyone on set thought she was hot, including Schlatter, with whom she had a brief, torrid romance -- while playing, it must be said, his older sister," Nelson writes in the May issue of GQ. "To we immaturions on the show, this seemed extra-hot. Like performative incest."
Nelson also shared some insider info on what it was like to work with Aniston before she became an A-lister.
"To Aniston worshippers, I can offer little dirt," he says of the seasoned movie star. "She was lovely, kept to herself on the set, smoldering a bit like her outraged character, 17-year-old Jeannie Bueller. She was a brunette then, with none of Rachel Green's bob or self-possession."
Since their Ferris Bueller days, Shlatter went on to marry Colleen Gunderson, with whom he has three children. Anniston, on the other hand, went on to marry and divorce Brad Pitt and is currently engaged to Justin Theroux and filming the comedic drama Cake.
