Jessica Alba was contractually forbidden from making eye contact with the likes of Luke Perry and Tori Spelling while working on the hit series BEVERLY HILLS, 90210 in 1998.
The Sin City star, who is currently dating film producer CASH WARREN, was shocked by the behaviour of her fellow actors on the set of the American high school drama.
Alba, 25, says, "I don't really know why. Maybe because the leading characters were so popular they didn't want other actors looking at them.
"You wouldn't be allowed to talk to them unless they spoke to you first. It was bizarre. But I guess that's what happens when you become a big star.
"A lot of actors get away with murder on set, but I always like to be part of the crew."
