Welcome back to the Tournament of THG, where fans vote on the most popular star of 2011! The concept is simple: Pick your favorite of the two stars in each poll. Done.
The semifinal round (final four) starts Monday, so this is your last chance to cast a virtual ballot in all four quarterfinal contests. So far, some are closer than others.
Katy Perry, Demi Lovato, Robert Pattinson and Miley Cyrus are ahead at the moment, but that could all change with a late surge. Only time - and you - will tell!
Who will advance to the next round? VOTE below (and after the jump)!
