"Gossip Girl" had a good run. It had six top-rated seasons and remained exhilarating until the end. But all good things must end and, in 2012, the curtain finally fell on the drama series filled with beautiful people and dashing fashion statements.

But is it really over?

Oh well, it looks like "Gossip Girl" is still very alive in our hearts which is why Michelle Trachtenberg's simple act of posting a "Gossip Girl" cast throwback Thursday photo made us all feel nostalgic.

The "Sleepy Hollow" star posted a photo of her with Chace Crawford and Penn Badgely, who played Nate and Dan respectively, on Instagram. She says in was her favorite behind-the-scenes photo.
