'Girls' Star Zosia Mamet Is Letting Her Real-Life Boyfriend Date Shoshanna

Mamet previews what's in store for Shosh when the HBO series returns Sunday and adds Evan Jonigkeit to the cast.

Watch out, NYC! Shoshanna is single and very much ready to mingle. When season three of HBO's "Girls" kicks off on Sunday, Zosia Mamet's uptight alter ego is back on the dating scene after breaking up with her sarcastic older boyfriend, Ray. And, from the sounds of it, she doesn't mind playing the dating game.

"It was definitely a different experience sort of unbuttoning this very buttoned-up character, which was a challenge and also a lot of fun," she teased to MTV News earlier this week at the season premiere of "Girls" in the Big Apple.

Among her suitors this season will be her real-life boyfriend, "X-Men: Days of Future Past" star Evan Jonigkeit.

"I hope that they'll like it; we're giving them a very different Shoshana. So I hope that they'll go along with her. But, I think that he's hilarious and brilliant," she said. "And I think that they definitely, they play off each other in an interesting way, so I hope that it will make for good comedy."

In addition to her love life, she's really stepping out of her comfort zone on Sunday's premiere. During the episode, she hits the road with Hannah (Lena Dunham) and Hannah's boyfriend Adam (Adam Driver), forming an unlikely friendship with the latter.

"It was interesting. It was definitely exciting and bizarre reading that first episode and knowing that we were going to act together and doing it was an incredible experience," she gushed. "I think that we took these very odd characters who had always been super separate and put them together and they oddly fit really well, which none of really knew how that was going to play out, but it was a happy surprise."

While Shosh's pals are all trying to figure out their lives post college, she's still in school. And, so, she's left to watch her friends, like Marnie, unravel.

"I think that she's so concerned about having it together that she's not really concentrating on how they don't," she said. "But throughout the season, I definitely think that becomes more of an issue for her, is the fact that her friends are kind of falling apart."
