Not being a "royal watcher" I had no idea this was a thing, that is, that Harry's wife likely faked her pregnancy. I only discovered in conversation with a fellow conspiracy theorist who is a woman, and thus her topics of interest are slightly different than mine..

There is plenty of evidence. We see it through a combination of pictures showing inconsistent belly size taken only days apart, as well as pictures that show her doing things quite difficult to do (if not impossible) for a pregnant woman, like squatting in high heels, and just the way her body looks in staged photos. Nobody who knows a real woman in her late 30s/early 40s has a belly that defies gravity like that.

Plenty of articles and videos offering evidence and "de-boooking" out there. But here is a good collection of pictures that tell the tale.

One last thing. If it's ever proved the there was a surrogate, than this means the baby is ineligible for the thrown, even though it's way down the line. Apparently the rules are the baby must be born "from the body."
