At last night's Guess boutique party, Michelle Trachtenberg dished on the relationship drama we'll come to see on the next season of Gossip Girl. But that's not all she revealed; turns out, M.T. has a nearly photographic memory when it comes to her character's manicures.

"Not a lot of people know this, but I like to change Georgina’s nail polish color," Michelle told us. "It’s very reflective of the season. When I first came on I was wearing the Chanel that was crazy limited [Blue Satin]. In the second season, I wore Essie Wicked on my fingers. At the very end, when I was enrolling into NYU, I had a cobalt blue. For this season, we start out at first with Essie Berry Hard and now this is the OPI That's Hot! Pink. I’m really serious about her nail polish!"

We'll keep you spoiler-free, but if you're dying to get a glimpse of what her character's manicure will look like, Michelle is sporting OPI That's Hot! Pink in this picture. Now you know.
