Celebrity transformations... There's something fascinating about how these stars have changed their appearance in just a few years time. Whether it is a diet, a great lifestyle or plastic surgery, the mindblowing before and after photos will definitely either amaze or inspire you. Scroll down for some major celebrity face transformations!

Some dare to admit that they've had plastic surgery or fillers, while others blame their new face to a different diet, stress, growing up or aging... you name it. The differences are very obvious, that is for sure.

Bella Hadid
The super model is just 19 years old, but she made quite a commotion when older photos of her showed up online. The difference between her nose then and now is pretty big: that is not just a case of great contouring.

Kim Zolciak
Real Housewives of Atlanta-star Kim Zolciak went for the classis Hollywood face make over: a new nose and some heavily injected lips.

Ariana Grande
Ariana's make over did not just include a new hair color, a tan and growing up. Looking at the before and after photo, there seems to be a pretty obious difference between her nose and lips.

Renee Zellweger
Wasn't Renee the biggest shocker when she presented her new look on the red carpet last year? The best part was: she claimed had nothing done. Nothing. Comparing these photos, Renee does not only seem to have less wrinkles on the right photo; her eyes are more opened up and lifted and her lips actually look smaller.

Kylie Jenner
Obviously, Kylie Jenner is known for getting lip injections when she was just 17. The now 19 year old queen of Instagram does not only seem to be sporting new lips, also her nose seems to have gotten some work done.

Charlotte Crosby
Charlotte has had quite a body transformation, but when she says she's done it all by working out and no surgery: that seems legit. Her face on the other hand? Seems to have had quite a bit of work done on the lips and nose.

Jenni Farley
Jenni doesn't seem to have had much done to her face surgery wise, but fillers here and there do make a big difference. Especially in her lips, which look way fuller in the after photo.

Emily Ratajkowski
Emily Ratajkowski, the girl who danced butt naked in the Blurred Lines video (did you know?) has not changed that much over the past couple of years. Her nose looks a little more refined and her lips actually look like they are smaller now... Did Emily go for a downgrade instead of a lip upgrade?
