We've waited all year for this, you could say we've waited decades for this. There's been videos and speculation for months, but tomorrow it is finally here!

That's right; it's Miley Cyrus' 21st birthday takeover on MTV!! It's an eight hour block of programming for Miley and by Miley! Featuring the debut of 21 Candles: Miley's MTV Moments, a re-air of the documentary Miley: The Movement Deluxe Edition and episodes of her favorite shows "Awkward" and "Snooki and JWOWW". You can even tweet birthday wishes to Miley using the hash tag #HappyBirthdayMiley. How clever! You can tune in at noon EST. It's not like there's anything else on television on Saturday.
