Beyonce reveals single inspiration

Beyonce Knowles has revealed the inspiration for her hit single Irreplaceable.

The singer has said that she wanted to empower her female fans by encouraging them to end bad relationships, following her experience of playing Deena Jones in Dreamgirls.

"Because I had been playing this character who was so caged, I had to do something with all that energy I'd been holding inside," she explained. "So I probably made my most emotional, aggressive record ever. I was able to be things I'm not.

"It's a celebration of a breakup and makes women feel like they're worth more. I'd never had so many women say that they'd put on the record [to help them] not pick up the phone and take him back. I'm walking down hallways and see fans yelling 'To the left, to the left.'"
