Listen to Jessica Simpson on iHeartRadio

(Yahoo!) - Oh baby! Only four and a half months after giving birth to her second child, Jessica Simpson is looking better than ever. The songstress turned fashion mogul tweeted out an Instagram pic on Friday, Nov. 15 that showed off her famous curves and newly whittled waist.

In the snapshot — which was taken to promote her JSimpson collection — the 33-year-old bombshell lounges seductively by the pool in what appears to be a white one-piece swimsuit with a plunging neckline. Though the image is artistically blurry, it's easy to see her hourglass shape and curtain of blond locks. In other words, her post-baby body is pretty much the bomb.

This reveal comes on the heels of her first full-body shot from her Weight Watchers commercial shoot. Clad in skinny jeans and a white button-down shirt, Jess looks happy and healthy as she stomps through some kind of… er… field. But the new poolside shot highlights her toned arms and flat abs even more.

And it seems that she's loving her new body as much as we are. Just a few weeks back, she was spotted on a date looking fierce in an impossibly tight black dress that hugged every inch of her. Arm-in-arm with Eric Johnson, she seemed pretty much ready to take over the world.

Perhaps, after receiving so much criticism for her body over the last few years (both while pregnant and not), Jess has finally gotten to a place where she is content with her shape and knows what she needs to do in order to look and feel her best. While we'll have to wait and see how her final physique turns out at the end of all of this, one thing is certain: Whatever she's doing these days, it's working.
