Jessica Alba's acting gig on the original "Beverly Hills, 90210" TV show was not her favorite job.

The actress, 39, played a teenage mom named Leanne for two episodes in 1998 and shared a scene with Kelly (Jennie Garth). While on set, she alleged that there happened to be some bizarre rules.

“On the set of '90210,' I couldn’t even make eye contact with any of the cast members, which was really strange when you’re like trying to do a scene with them,” Alba claimed on an episode of Hot Ones.

“Yeah, it was like, ‘You’re not allowed to make eye contact with any one of the cast members or you’ll be thrown off the set,'" she further alleged without revealing who said that to her.
