Melissa Joan Hart just reunited with Sabrina the Teenage Witch costars Nate Richert and Beth Broderick, and fans couldn't believe how different Richert looks! The main difference? Gone was the floppy boy-band hair of yore, with the former actor instead rocking a much more grown-up flat cap. Hart posted a selfie with her former costars on Instagram, captioning it, "When the magic fam comes together! @bethabroderick @thenaterichert." Nate Richert hasn't done much acting since 'Sabrina' ended.
