Attention, Upper East Siders:

Have we got the ultimate quiz for you!

Gossip Girl may have gone off the air in 2012, but we just can't let it go.

As many loyal readers may know, we once ran a fansite called Gossip Girl Insider.

It eventually morphed into TV Fanatic, but we were there from the first Dan eye roll to the last time Chuck Bass reminded someone that he is Chuck Bass.

We miss the show every single day.

So we saw little choice when we stumbled upon the following quiz but to share it with our fans, many of whom came over to TV Fanatic form Gossip Girl Insider (thanks!).

It asks one simple question: Are You Blair Waldorf Or Serena van der Woodsen?

And it takes you through a number of vital inquiries in order to get at the answer. Ready? LET'S PLAY!
