Lena Dunham's Saturday Night Live promos were just revealed and the young actress/writer ditched Kate McKinnon after promising to show up topless.

Dunham's promos for her maiden hosting gig on SNL with staff joke-ster McKinnon are out now. In the clip Dunham is seen wishing she could editorialize the script, directing the sketch and disapproving of McKinnon's outfit -- "she looks like a slut witch."

Dunham dishes out cinematographic advice -- "Shouldn't the shot be tighter, I feel like we are losing the intimacy between us?" she says -- and also advises McKinnon --"You're doing great but could we just do a take where you bring up the vulnerability."

McKinnon and Dunham are also seen celebrating the fact that they are both "young feminists."

In the last take for the promo, McKinnon shows up topless and directs mock-aggression at Dunham, who is still donning a loose shirt. She says she chose not to wear anything as the two of them had decided not to and Dunham failed on her promise. Dunham just shrugs saying she changed her mind while McKinnon expresses exasperation about the fact that she has to go to give a lecture at a high school after the shoot.

Dunham has been parodied on SNL before in an episode hosted by Tina Fey in September last year. The sketch which took on Dunham's hit HBO series Girls, showed Hannah and three friends -- Marnie, Shoshanna and Jessa -- with Fey playing a new character, Blerta, Hannah's new Albanian roommate. Fey hilariously amplified the girls' obnoxious issues, contrasting them with the dire circumstances Blerta came from. 

Dunham's episode of Saturday Night Live is scheduled to air on March 8.
