Well, she's playing the media for sure by staying silent.
I wouldn't say she's out of shape based on that pic. I've had my worst "food babies" while running 60-70 miles per week. They tend to stick out more when the person's otherwise fit. And they go down quickly, in an hour or two.
As to ridiculous, well......That's already the case, no?

Because announcing, then deleting, if it's true is, well, ridiculous.

In a situation like that, you say something quickly one way or another b/c it all came from you to start with. Very different from a situation where a kook randomly "announces" on your behalf (I wouldn't be in a rush to correct rumors from random internet people either if I were a celebrity).
No opinion on my end at this point; I'm just reserving the congrats until she or the dad (or maybe Venus or someone like that) says something.
