Gossip Girl's 100th episode left viewers in shock when infamous blogger's identity was revealed.

So, who is keeping an eye on New York's elite?

It's none other than Georgina Sparks!

The final scene of last night's episode featured a camera shot of Gossip Girl typing away at her blog. No biggie, right? The camera then panned up her arms to reveal Georgina with Blair's wedding bouquet placed next to her laptop. As if Blair marrying Louis wasn't shocking enough.

But is Georgina actually Gossip Girl? Yes, she's hell bent on ruining the lives of NYC's favorite 20-somethings, but does the dark-haired vixen have what it takes to be the most sought-after blogger?
