Welcome back, readers, to the 1st annual Tournament of TV Fanatic. It's time for the semifinals!

We're asking fans to choose their top CW stars and are conducting surveys among favorites from across the network. The concept is easy: Pick your preferred actor/actress from the pairs in each poll. That's all it takes!

Today, the next round begins with Ian Somerhalder against Leighton Meester!

In the quarterfinals, Ian (our #1 CW seed), Leighton (#4), Paul Wesley (#6) and Jensen Ackles advanced to the final four.

More than 45,000 votes were cast last round. Let's top that here in the semifinals! So which star do you love most, TVD's Ian or Gossip Girl's Leighton? VOTE:
