"See...now this is why I stay off Twitter. Just making stuff up for no reason...weekly," said her post.
The false rumour actually appears to have started on TikTok, where someone shared a video that seemed to look like an ultrasound from Zendaya's Instagram account.
The video ends with a clip of Kris Jenner dancing along with text saying "just got #krissed."
"Krissed" is a new Kardashian-inspired TikTok meme for getting pranked, but it seems that some people still haven't caught up and are taking it for truth.
In another TikTok video posted by @robairesbussy, Zendaya looks like she is walking beside boyfriend Tom Holland, although the image seems to have been tweaked to give her a baby bump. The video also ends with a "Krissed" disclaimer.
Eventually, the prank took off on Twitter with actual rumours of her pregnancy swirling and various people tweeting about it.
"Zendaya only got pregnant to make me jealous," said a tweet by @sammerlammer.
Even Lil Nas X weighed in on the frenzy.
"I hate twitter because I'm sitting here about to congratulate Zendaya via dm about a baby that doesn't exist," he tweeted.
The actress eventually set things right on Instagram and blamed Twitter for the false reports, although TikTok is clearly part of it, too.
In a post that followed, she stated "Anyway, back to filming Challengers."
So sorry (not sorry) folks -- there are no Zendaya/Tom Holland babies on the way yet!
