She is proving that women can be married with children, and still be sexy. Women are afraid of being monogamous sometimes, because they feel like they lose themselves to please the "look" of a wife for a husband.
She is challenging that by saying, why? I am going to be even sexier because as a woman, I love my body and curves, and not afraid to show it. You know why? Because she knows it is only for her husband anyway.
I think she will challenge that stance more and more this era.
