The Girls actress hosted the hit US comedy sketch show for the first time this weekend.
And E! News reports Lena partied after the show with Taylor, Girls guest star Jenna Lyons, Mean Girls’ Daniel Franzese and SNL cast members Vanessa Bayer, Bobby Moynihan and Aidy Bryant.
The group appeared to be having a great time at Asselina restaurant in downtown Manhattan in snaps uploaded to Daniel’s Instagram account.
"Live from New York it's the @nbcsnl after party with @girlshbo star @lenadunham and #meangirls homie #RajivSurendra and me @whatsupdanny!," he wrote next to an image of himself with Lena and actor Rajiv Surendra.
“Best party ever,” Daniel later captioned a photo of himself with Taylor.
Lena sparked controversy during her SNL turn after spoofing the frequent nudity of her Girls character Hannah Horvath in one skit.
In the sketch, the Girls episode unfolds in the Garden of Eden, with Lena’s character telling the story of “the first girl” opposite Taran Killam as her boyfriend on the hit show.
“Adam, a snake just talked to me. Is that normal?" she asks him.
"I just want to know what we're even doing here. Are we like man and wife or is it this situation where there's, like, all these other girls and I'm going to find out from one of the animals?"
The actress didn’t seem fazed by the fuss over the sketch, however. She logged onto Twitter after wrapping the show, gushing: "Cannot overstate how joyful this experience has been. I have always loved you Saturday Night Live, but now I am IN love with you."
