True, but I already admitted that I don't really understand her actions.And the photos are real anyway, so regardless of my general opinion about Beyonce, these photos are VERY strange.
They're actually not once you've seen the video.
The dress is obviously cut to accommodate the bump, and it's expensive so of a decent thickness, and when she sits down the material rises up briefly until she pulls it down again. There's nothing weird about it.
The only way to avoid it would be to glue the dress to her skin.
She might have been looking stressed because the dress rode up and she was concerned about flashing the other person, not because she had a fake squishy bump
