How did Justin Timberlake celebrate his Grammys performance on Sunday night? By releasing a new track off his upcoming album, The 20/20 Experience.

You can download "Mirrors" on iTunes now if you pre-order the album, which will be released on March 19.

The Biebs, who didn't receive any Grammy nominations, tweeted a recording of "You Want Me," writing, "its not finished but heres a little part a song I'm working on."
