Amanda Seyfried - Amanda Seyfried Quit Smoking To Protect Voice For Les Miserable Audition

The Mamma Mia! star dumped her cigarettes and hired a vocal coach to ensure she could hit the high notes during her audition, and her efforts paid off - she has been cast alongside Hugh Jackman, Anne Hathaway, Russell Crowe and British actress Samantha Barks in director Tom Hooper's upcoming movie musical.

Seyfried, who trained in opera as a teenager, tells Glamour magazine, "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."
