The as-usual completely uninhibited Hannah Horvath (Lena Dunham), clad in a sports bra and shorts, sweats it out in a dance class in the Season 5 video teaser for HBO’s Girls. Her mom even shows up (perhaps a sign that she’s getting out and buffing up following her divorce?). The video text reads “Dance Like No One Is Watching” … and she is. HBO previously announced Season 5 of Girls will premiere on Sunday, February 21.

Dunham executive produces along with Judd Apatow, Jenni Konner, Ilene S. Landress, Bruce Eric Kaplan, Murray Miller and Paul Simms.
