Which Teen Mom Is Nearly Unrecognizable in Her Prom Flashback Pic? (PHOTO)

The upcoming Teen Mom 3 star is 19 now and is working toward her social work degree, but back in the day, she was just a small town girl going to prom with her mohawked pals.

In what looks like a white (or light-colored) dress and her hair in a gorgeous updo, we wish we could see her this dressed up all the time! But alas, this is just a throwback photo, which she Instagrammed a few days ago.

Katie captioned the pic, “An early tbt but this was too adorable not to share #tbt #prom #firstboyfriend #adorable,” and we definitely agree. Too cute for words!
