Jennifer Lopez: four months post-baby in a bikini?

There was absolutely no reason for Jennifer Lopez to scamper off to a remote getaway in Spain to bare her post-baby bod in a bikini.

Considering she only recently had twins (Max and Emme), the singer-actress looks pretty darn good.

But don't let those harsh Brazilian fashion critics, who got all bent out of shape about Karolina Kurkova's flabby behind, see this photo.

And while we're on the subject of poundage, shouldn't Marc Anthony beef up bit? Dude is so scary scrawny.
