Steven Tyler wants to pay it forward, and he did so in a big way Wednesday when he opened Janie's House for abused and troubled girls.

Steven was on hand for the ribbon-cutting ceremony just outside of Atlanta and his heart was busting with pride.

It's a pretty incredible place ... the facility can house and provide therapy to 30 battered and sexually abused girls. It's the first of its kind launched through Steven's Janie's Fund.
