Glee celebrated their 100th episode with a two-part episode and a guest appearance by a familiar Gossip Girl hottie – Chace Crawford.

According to Buddy TV, Crawford will be playing a “Yalie degenerate” and Dianna Agron’s love interest.

E! News caught up with the blonde beauty at the Bulgari Decades of Glamour party at the Soho House in L.A. where she spilled that the duo would share a kiss.

Despite the musical television show, Crawford will not be singing.

“He’s not singing,” Agron said. “Although, I’m sure he can…He said that he can’t, but I think he can. I’ve heard him play around a little bit.”

It is unknown how much screen time Crawford will have, considering the role of Quinn’s boyfriend is not a huge part.

The special Glee episode will also include Gwyneth Paltrow, who is reprising her role of substitute teacher, Holly Holliday. Kristin Chenoweth is also reported to be stepping into her previous role as April.

Glee returns with the two-part episode on March 18 and March 25 on Fox at 8pm.
