Blonde bombshell Kimberly Wyatt has revealed that when she was in the Pussycat Dolls, the group's management were always putting pressure on the girls to 'stay in shape' and it was a real threat because they all knew they were replaceable.

Speaking to Health and Fitness magazine, the beauty explained that it was a stressful time: "There was a lot of pressure from the management label to stay in shape. I knew we were replaceable, so the pressure of wanting to stay in the group kept me in the gym."

Wyatt went onto add that she now makes sure she always has time to work out because it makes her feel better and gives her motivation:

"Exercise absolutely has to work with my life and be something I can live with. It's a priority because it's a source of stress relief and fuels my determination. It's all about keeping my workouts mixed and having something to look forward to."
