These days, a lot of celebrity moms who have just given birth can go back to wearing swimsuits after only a few months.

The usual reaction is, "Parang hindi nanganak."

Some stars were lucky to have tummies that shrink right away.

Some had to go through strict diet and regular exercise, while others got some help from their go-to beauty clinics.

Some are still a "work in progress."

But regardless of how they achieved their pre-pregnancy bod again, all of them believe that motherhood should not be made an excuse to be losyang.

As Marian Rivera and Jennylyn Mercado put it, "Bawal pabayaan ang sarili."
