Actress Cameron Diaz is approaching 40-years-old, and wants to keep her fit physique in tip-top shape before having children.

She said:

“If I was having a child I would think that I would want to be the strongest I’ve ever been in my life.

“If I was squeezing a baby through my body, if I was going to be carrying it around, it I was going to then be afterwards having sleepless nights, I would just want to be in the best shape of my life.”

I think she’ll still be in really good shape after having a child – she’s totally going to be one of those fit mamas!
