One of our favorite funny girls, Lena Dunham, is set to host Saturday Night Live for the first time tonight! While rehearsing for her upcoming gig, Dunham shared this photo on Instagram from the studio alongside SNL cast members Aidy Bryant, Sasheer Zamata, and Vanessa Bayer. "Girl pile in Studio 8H," the star captioned the image of the smiling ladies. The Girls creator is a self-proclaimed SNL superfan, and it seems like she can't wait to host the show. "Thank you for the SNL love. Dream come true," Dunham tweeted of her hosting debut. Be sure to tune in tonight March 8 at 11:30 p.m. EST on NBC to watch the show—if the series of promos are any indication, you won't want to miss it! Want more Lena Dunham?
