“All the notes are accurate. I am playing the actual notes of the music…but [on set] it just sounds like a cat in heat,�? said Alba. Even though she practiced for an hour and a half each day starting with pieces like “Twinkle, Twinkle, Little Star,�? she admitted, “It’s impossible!�?

In other news, Jessica Alba has revealed that when she worked on the hit show 'Beverly Hills 90210' in 1998 she was contractually forbidden from making eye contact with the likes of Luke Perry and Tori Spelling reports HollyScoop. com

She 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."
