MTV reports that some of the top contenders as announced last week include the obvious Miley Cyrus, Taylor Swift, Jonas Brothers and “Twilight”. Justin may not be nominated for anything this time around but I am more than certain he will next year.

You can start voting on Nick.com from today for your favorites! FYI Miley is up for four awards competing with recent awards-show favorites Beyoncé, Lady Gaga and Taylor Swift in the Favorite Female Singer category.

Check out the list of nominees on J-14

Who do you think will win the Favorite Female Singer category?

I have a feeling Taylor Swift will rule!
