Sorry Internet conspiracy theorists, Beyonce‘s rep claims her baby bump is 100% authentic … despite a video in which her stomach appears to fold over, leading many to believe she was wearing a prosthetic.

B’s rep told ABC … rumors about the singer wearing a fake baby bump underneath her dress are “stupid, ridiculous and false.”

Also, there are photos of Beyonce in a bikini … in which you can clearly see her actual, pregnant stomach.

So, there you have it.
