Grace Helbig and the Harts Star in 'Dirty 30'

If you haven't spent hours on end binge-watching YouTube videos by Grace Helbig, Hannah Hart, and Mamrie Hart, you've missed out on a huge life experience. But no worries, the hilarious trio has joined forces for a new project that you can't miss. After the success of their first crowd-funded film, Camp Takota, they've just released the trailer for their new comedy, Dirty 30.

Kate (Mamrie) is not excited about turning 30. While she's perfectly content with becoming a single cat lady, her friends Evie (Helbig) and Charlie (Hannah) are determined to throw her the party of a lifetime. With closet goths, out-of-the-closet lesbians, and fellow YouTuber Flula Borg in attendance, we're kind of offended we didn't get an invite.

Dirty 30 premieres in select theaters Sept 23. Watch the trailer below:
