Lena Dunham is not amused.

Upon learning that her HBO hit show Girls had been parodied in a porn titled This Ain't Girls XXX, the actress/writer/producer expressed her extreme dislike via a series of tweets.

Richie Calhoun, an adult film star who plays Adam Sackler in the parody, told XBiz the porn parody captures "the voice and tone" of the original. We see where he is coming from, since Girls does feature plenty of nudity and adult themes. Richie also says "they didn't have to do much" more than extend the sex scenes, make them non-simulated, and make them more provocative.

"It will be interesting to see what people will say about it, because with something like that, people would expect a really bold or nuanced statement," Richie says.

"Maybe it will be like that or maybe people will say, 'This is an outrage. This is terrible!' I'm not really sure."

Well, for the record, Lena falls in that second camp.
