Michelle Trachtenberg is making us really miss our favorite Upper East Siders. Yesterday, the former Gossip Girl star, who played the girl everyone loved to hate, Georgina Sparks, posted a snap of herself alongside co-stars Penn Badgley, aka Dan Humphrey, and Chace Crawford, otherwise known as Nate Archibald.

"#tbt One of my favorite pics behind the scenes of #gossipgirl with these two handsome gents. #trouble #georginasparks #xoxo," she captioned the photo along with a kiss emoji (below). Trachtenberg may have been an enemy on screen, but when the cameras were turned off, it's clear that these co-stars were most definitely friends.

However, this isn't the first time Trachtenberg has made us miss this cast of the hit show. Earlier this year, she posted a selfie of herself with Crawford. Gossip Girl, forever.
