Jessica Simpson Tweets New Photo of Baby Maxwell Drew

Now, days later, the 32-year-old singer/designer has tweeted visible proof: a photo that reveals her already sizeable baby bump.

In the photo, Simpson stands in front of a mirror with an iPhone -- modeling a pink and purple floral two piece swimsuit and a coverup -- with her bare bump and bikinied bosom in full view.

She accompanied the photo with the caption, "Bumpin' and Proud."

Jessica is currently on a family beach holiday in Hawaii -- which explains the fashionable bikini -- with her fiance, Eric Johnson, and their seven-month-old daughter, Maxwell.

The image of Simpson is in stark contrast to a slimmed down Jessica on the cover of the January issue of Weight Watchers magazine. In the issue, she shows off the results of her 50 lb. weight loss and talks about how she slimmed down after the birth of her daughter.

"I’m crazy about smoothies, so I bring fruit chopped up and ready to go," she explained to the magazine.

"That way, I can sip the same smoothie all morning long between takes. If it thins out, I put it back in the blender with crushed ice for a few minutes."

Simpson will ditch the Weight Watchers diet now that she’s pregnant again. But ads showing off her 50 lb. weight loss will continue to appear, as well as a commercial in which she announces her second pregnancy.

We're gonna go out on a limb and predict that there will be another Demi Moore-style magazine cover of Simpson's bare bump.

Once you've done it for the first child, you kind of have to do it for the second.
