Amanda Seyfried's stage fright is stopping her from performing on Broadway.

The 40-year-old actress used to dream of starring on Broadway, but Amanda admits that she'd be too anxious to sing in front of a live audience.

Speaking about the challenge of singing in The Testament of Ann Lee, the new historical musical drama film, Amanda told Vanity Fair: "I'm always striving to just be a little better. But this movie has made me step back a bit and appreciate what I already have.

"My voice coach is like, 'Where have you been' because I've known her for so long, and I'm like, 'I'm okay now.'

"I think my plan was to do a musical on Broadway, and then I made the decision to never put myself through that — because to be honest, my stage fright is like, life's too short.

Amanda has actually found it liberating to accept that she'll never sing on Broadway.

She said: "When I decided that I wasn't gonna do that for the foreseeable future, I just took a step back from voice lessons.

"I remember that day on set, actually. I was in Budapest, and I remember thinking I'd had two nightmares back to back about doing this musical on Broadway. I was just talking to my agent in a little break in my corseted dress and thinking, 'I can't" put myself through that.'
