Beyonce Knowles at Launch party for her new CD 'B'day' at Volstead, London, England - 16.08.06

The former DESTINY'S CHILD star was so inspired by playing a downtrodden singer in upcoming movie DREAMGIRLS, she cancelled vacation plans to hit the studio.

She refused to let anyone know at her record label and so raced through the recording, giving every track a sense of desperation and angst.

She tells MTV News, "I had so many thing bottled up, so many emotions, so many things I wanted to say that while I was supposed to be on vacation, I snuck away to the studio and recorded this record in two weeks and that's why most of the records are so aggressive.

"It's the record that women need to hear."

And she admits even she's shocked by her screaming vocals on new tune RING THE ALARM.

She adds, "I'm screaming at the top of my lungs; I don't even scream, but I had a lot to scream about.

"Women clean men up sometimes... They dress different, they learn a lot of things, they learn how to be a man and then if they dog you out and you move on and another woman just benefits (from) all those things.

"I'm saying, 'Ring the alarm, I've been through this too long, but I'll be damned if I see another chick on your arm.'"
