Guess Who

Before this sweet boy wearing striped overalls turned into an American actor and comedian, he was just a cool New York City kid, cruising the concrete jungle with big dreams of making it in the entertainment industry.

After appearing on "The Rosie O'Donnell Show" back in 1996, he went on to act on "The Amanda Show" and made his film debut in "Snow Day".

Yes, he's probably most known for his starring roles on Nickelodeon during the early to mid-2000s, but he's also a popular YouTuber often discussing his comedic lifestyle to his 3.5 million subscribers.

Before this bashful little kiddo with beautiful blue eyes from Watchung, New Jersey turned into an American actress, she was just playing with her four older siblings, acting silly for the camera, and going off to study drama in New York City.

She's acted on several iconic shows ... She first rose to stardom playing the role of Donna on "That '70s Show", but you may also recognize her in a jumpsuit behind bars. Alongside Emily Blunt, she was in the thriller film "The Girl On The Train."
