'Girls' brings in a new guy: Zachary Quinto lands guest star role

zachary-quinto-girls-hbo-guest-star.jpgSo far we don't know much about the plot of "Girls" Season 4, but this week we got a tiny clue as to what's to come.

Zachary Quinto was spotted out in Brooklyn (June 18) with "Girls" creator and star Lena Dunham, filming a scene for the HBO show.

The pair were seen wearing matching blue smocks that read, "Ask me my name."

Quinto's impressive list of credits includes "American Horror Story", "24," and "Heroes," as well as portraying Spock in the latest "Star Trek" films. 

Curious what Quinto's arrival means for "Girls", did Hannah decide to kiss her graduate school dreams goodbye?

"Girls" is set to return to HBO in early 2015.
