Miley Cyrus has been blonde for what seems like years now, but she's finally gone to the dark side ... and we love it!

The 24-year-old superstar posted the selfie above on Instagram and wrote, "Debutin my new liewkkkk #mileyonsnl #oct3," and we can't wait to see the whole thing when she hosts the season premiere of Saturday Night Live tonight.

Miley has been posting teasers this past week for the show, and she'll also be the music guest tonight. On Friday Miley was photographed filming a sketch for show in NYC, and she was wearing a brown wig for that, but the snapshot above seems to be her real hair. Well, plus extensions, but here's to hoping she hangs on to this look for a while, because we love it!
