Girls is beaming up Zachary Quinto for a guest spot in Season 4.
The Star Trek star and American Horror Story alum is set to appear in one episode of the HBO comedy's upcoming new season, Mashable can confirm.
Details on his character were not made available by the network, but based on photos captured on set of Quinto and Lena Dunham, their characters will cross paths during some sort of volunteer duty involving recyclables. (Quinto is really working his "Ask me my name" vest.)
Quinto can currently be seen on the New York stage in The Glass Managerie, while his possible return to AHS and the Heroes miniseries reboot at NBC remain up in the air.
Girls returns in 2015, although no premiere date is set yet.
