Actress Bipasha Basu doesn't fear being sidelined by the popularity of newcomers because she believes it's the audience who decides the longivity of an actor.

"The audience's support helps there. You last for so long because people like you. There is no science, no physics behind it. You can just do good work," Bipasha told.

The actress has been a part of the industry for over a decade and has been a part of hit films like "Raaz", "Omkara", "Race" and "Bachna Ae Haseeno".
