Chris Lowe and Patrick Flueger: The Stars of "Spin" Get Romantic

The movie Spin (2007) is an indie multi-timeline, multi-viewpoint story about six hardbodies getting into trouble in a heterosexual L.A. nightclub, their lives all intertwined by dj Ryan (Patrick Flueger).  Chris Lowell plays a crystal meth user.

Chris went on to star in Veronica Mars and Private Practice, and in the movies Graduation (2007), Up in the Air (2009), and Love and Honor (2013).  As far as I can tell, he's never played a gay character.

Patrick Flueger, most famous as Jeremiah Hart in The Princess Diaries (2001), has guest starred in many tv series, and had starring roles in The 4400 and Scoundrels.  He has appeared in the secluded-cabin-horror Kill Theory (2008), the workplace comedy The Job (2009), Footloose (2011), and The Hatfields and the McCoys (2013).  As far as I can tell without seeing any of them, as heterosexual characters.

So I'm wondering about these photos.

Is there a gay romance going on here, or an unself-conscious bromance between straight guys?
