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
Yes, I get that.That's not what I find strange.What I find strange is the size of the "baby bump".In the red carpet of the VMA's she had a big bump, but in 3 out of the 4 photos that leaked today the baby bump is barely noticeable.Those new photos are not the only ones that I find strange.It's the comparison between these photos (October) and the VMA photos (August) that raise eyebrows...I don't know.It's her "baby bump", so she can do whatever she wants
