Kelli Berglund might've just dramatically switched up her look again! The Lab Rats actress posted a pic on Instagram with one of her besties and she has us thinking she can possibly be a blonde again.
We aren't 100 percent sure if this pic is just a throwback or if Kelli has dyed her hair. After all, she totally pulls off the blonde hair and her Instagram icon is a pic of her with her lighter locks.
Kelli later posted a super cute snapshot of her and her boyfriend, and her hair is back to brunette!
Girl has totally got us stumped but either way, she looks pretty fabulous!
