Hollywood actress Amanda Seyfried says she quit her social smoking habit because she feared it would wreck her voice and her chances of landing a role in the film adaptation of 'Les Miserables'.

The "Mamma Mia!" star dumped her cigarettes and hired a vocal coach to ensure she could hit the high notes during her audition, Daily Star reported.

"I was smoking cigarettes socially, like, every couple weeks. Then I started singing again, and if I'm spending all this money taking lessons, then there's no point in doing that.

"Everybody and their mother was auditioning for Les Mis, so I wanted to audition, but I wanted to be good," she said.
