Watch: Porn Stars Perform Car Karaoke

Fun, spontaneous and gay: three words Titanmen director Jasun Mark used to describe an impromptu music video he made with porn actors Jesse Jackman and Dirk Caber, as Towleroadtipped us off.

The trio sing to the tune of I Kissed a Boy, a remake of Katy Perry's hit song of (almost) the same name by Cobra Starship.

Jackman and Caber are a married couple, seen in the passenger seats of the karaoke video. Mark, who is also out and was driving, explained on the YouTube page that they made this at the end of a very long, grueling and exhausting week of filming.

Before we go on, think about what you do for a living, then take a moment to imagine what "a long, grueling and exhausting week" of filming gay porn is like.

Got it? OK then.

Mark wrote that the video "looks like it was shot through Instagram filters" because he had used the camera to shoot Caber diving into a pool and hadn't reset the white balance or auto-aperture for sunlight.

"Normally I'd say we should do it again," Mark posted, "but this was fun and spontaneous enough that we figured... meh... Besides, they live in Boston and I live in Los Angeles and that would be a long road trip."

Yeah, but just imagine how cool a road trip that would be with these three singing all the way.
