Gleeks, prepare yourself for Nate Archibald Chace Crawford!

The former Gossip Girl star is rumored to be appearing in the popular Fox series for its milestone 100th episode. To no one's surprise, an insider says that he'll be playing Quinn Fabray's love interest: "[Chace] will play Dianna Agron's boyfriend, whom she brings back to Lima to meet her friends." Also not surprising (hey, we've never heard him - can you blame us!) is that "his character will not be singing -- as of now."

Considering the fact that he's no stranger to teen dramas, the 28-year-old star seems to have fit in on the Glee set among his friends: "Chace is excited to work with [series co-creator] Ryan Murphy and his longtime friend Matthew Morrison... He knows most of the other cast as well."

Glee's 100th episode will air in two parts on March 18 and March 25.
