Before this lil' cutie with red hair and blunt bangs turned into an actress, she was just givin' some sass to the camera, attending college where she studied acting and theater, modeling and growing up in Scotland.

You may recognize her as Amy from "Doctor Who," Nebula in "Guardians of the Galaxy" -- which she buzzed her head for -- or in a big film with Dwayne Johnson, Jack Black and Kevin Hart.

Aside from the buzzcut, she's rocked many hairstyles over the years and shares her fashion game to her 7+ million Instagram followers.

Before these two siblings in matching 4th of July outfits turned into big stars, they were just two stripey sisters attending dance class and acting while gearing up for the firework show in Houston, Texas.

While one sister is known for her food blog and cooking show, the other sister was a busy Lizzie on stage! However, BOTH sisters were on a hit Disney show. And their mama is also in the entertainment biz, producing one her daughter's movies, "A Cinderella Story."

When these gals aren't runnin' it in Hollywood, they love spending time with their adorable kiddos.

Before this boy with bleach blonde hair turned into a social media influencer and was swingin' behind the wrestling ring, he was just throwing on his denim jacket and growing up with his bro in Westlake, Ohio.

Before this proud Phili-native turned into an American actor and comedian, he was running around the yard with his older bro, selling shoes and dreaming of being in the NBA before moving to the Big Apple ...
