O Music Awards Nominees Include Blake Shelton, Taylor Swift

Tonight at 7:30PM EST, MTV kicks off its third annual O Music Awards, an event that will run for 24 hours and take the form of a live-blogged, live-streamed, live-you-name-it bus tour through the South. Given the route -- Memphis to New Orleans -- it's fitting that two country stars, Taylor Swift and Blake Shelton, are among the nominees.

Taylor is up for two awards: Fan Army FTW, which honors especially devoted artist fan bases, and Most Extreme Fan Outreach, which salutes stars who've found innovative ways to interact with the public. The superstar's nomination in the latter category is due in part to her YouTube Q&A session, which has thus far drawn more than 5,500 user comments.

Blake, meanwhile, is up for Must Follow Artist on Twitter, which won't surprise any of his fans. The singer and "Voice" judge is a prodigious, often hilarious tweeter, and while he faces some stiff competition -- hip-hop drummer Questlove and Yoko Ono, of all people, are among the other contenders -- he's got a fighting chance.

Voting runs until showtime, so be sure to show your country colors and support Taylor and Blake. And while you're at it, show some love for AOL Music's own Contessa Gayles, who's up for Hottest Music NILF!
