Holly Madison's swimsuits are shrinking.

The new mom, who gave birth to daughter Rainbow Aurora in March, has been slipping into her bikini on a regular basis -- documenting her post-baby weight loss with a series of sexy shots.

Now, four months after welcoming her daughter, Madison's bikini bod is more impressive than ever and she's covering it up with as little material as possible.

If you got it, flaunt it, right?

The newly-engaged mom credits her weight loss to a strict diet and intense cardio.
