The actress/singer is currently starring in Glee creator Ryan Murphy's new project, Scream Queens, a horror comedy about a series of murders on a college campus.

While Lea admits she is usually up for anything when it comes to acting, she drew the line at possibly damaging her voice by screaming during the shoot.

"I refuse to scream on the show," she tells Women's Health. "Ryan got me in a (recording) booth one day, and I told him 'I'm screaming like twice and then you're going to have to use it the whole season,' because I'm a singer, and I was there with Ariana Grande and we were like, 'We can't scream, this is our gift.'

"So I don't scream, they just dub it in. But they say I do a really good scream face without having to scream."
