Not that this is a subject that's really worthy of much analysis, but... I don't think they're real.
And some full disclosure for you Jim-Pat, since we're simpatico on many things; I used that particular video for the gif because I thought they looked better than they do in other videos / photos of her that I've seen.
In the end, I don't think it matters. If you were motor-boating them, they're gonna seem real enough either way!
