The actress guest starred in two episodes of the show, and was unable to make eye contact with the leads.

Actress Jessica Alba recalls a strange experience from the time she guest-starred on a popular American show.

During “Beverly Hills 90210,” he was told not to make eye contact with the cast of the popular teen drama.

“On the set of ‘90210’, I couldn’t even make eye contact with any of the cast members, which was really weird when you’re trying to do a scene with them,” Alba said in an episode of “Hot Ones,” reports etonline.com.

“It was like, ‘You can’t make eye contact with any of the cast members or you’ll be kicked off the set,’” she added.

In 1998, Alba was seen as Leanne, a pregnant teenager in two episodes during the show’s eighth season. She shared the screen with Jason Priestley and Jennie Garth, among others.

The actress did not elaborate on who gave such directive and why.

“Beverly Hills 90210” aired from 1990 to 2000.
