This may be hard to believe, but it’s officially been 12 years since the TV show Unfabulous ended. Yep, the Nickelodeon series aired its final episode on December 16, 2007, and fans are pretty shook over how fast time has flown by. It feels like just yesterday viewers were watching Emma Roberts, Malese Jow and Jordan Calloway on their TV screens, and there’s not a day that goes by that they don’t miss it, TBH.

Fans may not know this, but there were actually a ton of celebrity guest stars throughout the three seasons that the show aired. Stars like Nicole Anderson, Miranda Cosgrove, Bailee Madison, Tyler Blackburn, Hayley Kiyoko, Nate Hartley, Maiara Walsh and more celebs made appearances on the show before they were famous! Wow, who knew?
