This seems like something that would be better served by saying it was on her Facebook page. I can see someone posting "I'm going to have a baby!! But don't tell anyone, it's a secret!" with that stupid clenched teeth emoji on Facebook but Twitter doesn't seem to be used like that. Maybe I just have a better timeline on Twitter than I do on Facebook.
Also, Mary Jo Kronk sounds like one of those women who always assume they are pregnant. I wouldn't go finding her baby registry quite yet Gladys until you see proof that she is with child. While we wait for proof that Mary Jo is pregnant, you can follow me on Twitter.
