The Sussex family have long been associated with bonkers conspiracy theories and outlandish online rumours - but this week, critics have taken their bizarre estimations to a whole new level.
After Meghan Markle and Prince Harry shared a series of sweet snaps from their daughter Princess Lilibet's fourth birthday celebrations on Sunday (8 Jun), a batch of social media users have convinced themselves that the youngster isn't real.
For those who haven't yet caught up with the couple's latest upload, Meghan, 43, and Harry, 40, took both Lili and their son Prince Archie, seven, to Disneyland to celebrate their youngest's big day.
Clips shared by the former Suits actress showed the birthday girl wearing a baby blue cap as she and her brother were led around the park, meeting an actress dressed as Elsa from Frozen and posing for photos as they ventured up a log flume.

Another image shows Harry posing with Lili - whose face is obscured by a pink heart emoji, in keeping with the family's plea for privacy.
A Mickey Mouse hat-wearing Meghan could also be seen introducing Archie to a Star Wars display in another.
"Thank you @disneyland for giving our family two days of pure joy!" she captioned the video compilation.

As we say, however, the collection has led to the continuation of a downright bizarre conspiracy theory about the Sussexes, primarily Archie and Lilibet, who are accused of being 'AI'.
Some critics of the couple have long been convinced Meghan and Harry - who have only begun sharing images of their children in the last six months, and always whilst hiding their faces - have been using body doubles for their kids.
The allegedly ever-changing colour of their children's hair colour has been used to support this particularly bizarre theory so far.

Others, meanwhile, have convinced themselves that the pair aren't even parents after all, believing Meghan donned a completely fake 'moon bump' whilst 'pregnant' with her daughter.
The odd series of theories have taken an unexpected twist this week following the release of her Disney snaps, however, with some critics believing she'd added their supposedly non-existent children into the photograph using artificial intelligence.
Looking closely at the most recent photos, one troll believes Lili is levitating whilst a 'disembodied hand' holds her up'.

Meanwhile, others questioned why the children appear to be dressed in rather different levels of attire.
"Maybe the fact they are all dressed to a different season!?" they pointed out.
"Was Summer hot for Lili to be on a Summer dress but cold enough for Archie to be wearing long a long sleeve-shirt and pants? Which is it?"
One aspect of this theory suggests that the distortion of several wooden planks in the photo implies that, even if the children were present, a nanny had allegedly been digitally removed.

"I'm guessing the nanny was standing with Lily in the original, where the floorboard is wiped out." a critic commented.
Some, meanwhile, believe that the fact that seemingly no other theme parkgoers spotted them enjoying their family day out supports the theory that they weren't there at all, as reported by The Mail.
It's not the first time Meghan has been accused of having 'altered' images, as a photo of her and Prince Harry for their seventh wedding anniversary was claimed to have been 'photoshopped' by some online users.
Meanwhile, another image of Prince Archie also saw others claim that there was 'something wrong with his toe'.
Tyla has reached out to Meghan and Prince Harry's representatives for comment.
