Kelly Rowland is officially the new cover girl for the forthcoming October Issue of Shape Magazine. Inside, she reveals: 'I work out five or six times a week. I feel better, look better, sleep better. As I’m getting older, the Rowland family trait of having bigger bottoms is taking its toll on my hips and butt. The other day, [my trainer] had me doing squats that were so hard I wanted to kill her. But my behind is getting higher and tighter. Exercise really does change your body.' If this isn't motivation? Your totally not serious. Lol.
