Earlier this week, the former X Factor judge took to the picture app to share a series of close-up snaps and while there'e no denying she appears utterly flawless in each and every one, some of her followers have noticed a change in her face.
Many even admitted that they had failed to recognise the N-Dubs star completely while scrolling through their feed, and a handful believe she has either gone under the knife or the needle.
Taking to the comments section underneath a photo that Tulisa captioned, "Rise and shine," one of her followers wrote, "Can't believe how different u look! I'll be totally honest if u had walked passed me in street and I'd not seen this on the net I wouldn't recognise u x still beautiful x"
Another said, "Still gorgeous but you don't look anything like you used to! Have you had gone in for surgery? I'm confused!"
Confused is the right word.
Speaking to The Guardian in 2014, Tulisa admitted to lip and cheek fillers to alter the shape of her face.
"Yes, I've had my lips done," she said, "and I'm happy with my lips. And I also had a tiny bit of filler in my cheeks [but] It really bugs me when people say I've had a nose job. That's just make-up."
The starlet went on to say, "So losing a stone, filler in my cheeks, my lips done and the contouring - and people do think, oh gosh, you so different."
Fast forward to this week and fans are still just as baffled (if not a little more so) by Tulisa's ever-changing look. She hasn't responded to any of the Instagram comments currently still racking up but it wasn't long before her followers leapt to her defence.
"How people can critisize her for changing how she looks is beyond me," one said. "It's her choice. Leave her to it.. give her a god damn break!"
Another said, "If she has had surgery she looks wonderful, not crazy like some celebs."
