MOST: Darren Criss as Blaine Anderson
Most of Glee’s newer cast members haven’t been around long enough for noticeably different “then” and “now” photos, but Darren Criss (Blaine) is one marked exception. Before he burst onto the Glee scene in November 2010 for Season 2, Episode 6: “Never Been Kissed,” the 23 year old was sporting quite a longer and curlier ‘do. Darren chopped off all those California surfer boy locks in order to take on Blaine’s snazzy, slicked-back hairstyle. Don’t get us wrong: the clean-cut Darren, 25, of today is still super (megafoxyawesome) hot, too. But our love of his Potter hair of yesteryear will never truly go away.
