HBO has not yet confirmed a return date for Girls, though production is underway as revealed in the first teaser trailer for the impending Season 4. Creator and star Lena Dunham shows off her impressive stunt skills, taking her bike out for a ride all on her own. Things don't end quite so well, and the stunt rider eventually has to be brought in. Check out the first footage from all new episodes, as Girls prepares for its return sometime next year.

In Girls Season 4, Hannah Horvath will be retreating to the Iowa Writer's Workshop to get away from a now very complex relationship with her boy friend Adam (Adam Driver).

Guest stars for next year's new batch of episodes include Natasha Lyonne, Zachary Quinto, Maude Apatow, Jason Ritter and Gillian Jacobs.

If you can't wait for Girls Season 4, Lena Dunham will be releasing her new book of personal essays Not That Kind of Girl: A Young Woman Tells You What's She's 'Learned', which will be in stores and available online September 30th.
