Of course, Bella's fans could only focus on one part of the caption.
"Are you having a baby??" one questioned.
"Yeah huge congratulations @willstokoe and @bellavarelis gonna be the hottest baby ever," remarked another.
New Zealand Bachelorette star Lily McManus even stated: "If you’re pregnant I’m going to start crying right here in the club."
Other guesses ranged from Bella dyeing her hair blue to buying a house, since in her picture she's standing on the steps of a house.
Some fans even suspected that Bella is about to debut a new blue butterfly tattoo. Last year, Bella had a butterfly tattoo done in honour of her late grandfather as the psychic she met on The Bachelor told her spirits can show themselves as butterflies and "ever since he passed they've been coming up almost every day."
However, former Bachelor Matty J had the best take on Bella's caption in our eyes.
"You’ve bought a property in the NSW hinterland to start breeding blue morpho butterflies !???" he guessed.
Not long after her post, Bella confirmed that she was not expecting.
"Guys I'm not fricken pregnant. I wrote 'baby blues' because my whole outfit was baby blue," she shared on her Instagram Stories.
"Some of you are close but I can't show you yet - you'll see shortly xx."
The former Bachelor contestant added: "Also come onnnn guys if I was pregnant I would've made the announcement 10x times for exciting. You know me."
"Idk how you guys managed to jump to the most extreme conclusion when two days ago I was showing you all 6 different types of cocktails I drank in one sitting."
Bella recently stated that she doesn't plan on becoming a mum soon.
“I’ll probably wait until I’m 28 or 29,” Bella replied to a fan in a YouTube Q&A with Will when asked if she's ready for kids.
However, it seems that the Bachelor beauty has found The One.
When Bella read the question “Do you see yourself marrying this man?”, Bella laughed and remarked: "Yeah I do."
