Come on, everyone is doing it!

Michelle Trachtenberg just joined the "cool" crowd. Like many other celebrities of the moment, the Gossip Girl villainess is trying her hand at jewelry design. She will collaborate with Coach on a jewelry collection under the brand's Poppy line.

This should be interesting. We don't exactly think of Trachtenberg as a fashion pioneer, but we'd love to see what she has in her jewelry box. We're guessing her goodie-two-shoes glow mixed with her bad-to-the-bone edge.

According to WWD, the line will be full of colorful crystals, faux pearls and intricate hardware. Glam on!
