Paul Rudd

Amy Poehler and Paul Rudd dressed in costumes last night on the NYC set of They Came Together. So far we've seen Amy and Paul kissing and attending a wedding, and now it appears they're getting into the spirit of Halloween. Max Greenfield recently wrapped his part on the project, but said working with Amy and Paul was "unbelievable." Amy and Max will have a chance to catch up on Sept. 23 at the Primetime Emmy Awards where both actors are nominated. Amy's in the running for lead actress in a comedy series for her role in Parks and Recreation, while Max earned his first Emmy nod in the supporting actor in a comedy category for his portrayal of Schmidt in New Girl.

Seth Rogen joined his Armani-clad wife, Lauren Miller, at last night's NYC premiere of For a Good Time, Call . . . Lauren wrote the raunchy comedy and costars in it with funny lady Ari Graynor, who chose a pink low-cut dress from Honor and Brian Atwood heels. Justin Long, who's reportedly dating Kate Mara, stepped out solo and adorably posed for photos holding his phone. Paul Rudd, Kristen Wiig, and Mad Men's Elisabeth Moss stopped by the afterparty to show their support for the project. Elisabeth debuted a short blond bob on the red carpet and turned heads in a sexy black cocktail dress. When asked if blondes really have more fun, Elisabeth joked that she is "so far." For a Good Time, Call . . . hits theaters Aug. 31.

Love was in the air on the NYC set of They Came Together yesterday as Amy Poehler and Paul Rudd shared a kiss. Amy wore a wedding dress for a few scenes, then changed into a shorter white frock for a make-out session with Paul. She also got a visit from one of her number one guys, her oldest son, Archie. The pair were full of laughs during one of Amy's breaks from filming.

Amy's busy with her latest big-screen adventure in the Big Apple, but she traveled to Washington DC recently to shoot an upcoming episode of her NBC series, Parks and Recreation. Amy shared a high-profile scene with Senators Barbara Boxer, Olympia Snowe, and John McCain that will air when the show moves to Fridays this Fall. The primetime comedy also earned Amy 2012 Emmy nods. She'll be going head-to-head against funny ladies Tina Fey, Zooey Deschanel, Lena Dunham, Edie Falco, Julia Louis-Dreyfus, and Melissa McCarthy in the outstanding lead actress in a comedy series category. The ceremony airs Sept. 23 — see the entire list of the 2012 Primetime Emmy nominees.

Cosmopolitan magazine played hosted last night for their annual Fun and Fearless Awards at NYC's Mandarin Oriental Hotel. The year's big honorees were Dakota Fanning, in Miu Miu, and Paul Rudd, who earned the female and male titles, respectively. Additional honors went to The Hunger Games hunk Liam Hemsworth, Grey's Anatomy's Jesse Williams, 21 Jump Street's Jonah Hill, a YSL-clad Freida Pinto, NFL star Adrian Peterson, Pretty Little Liars' Lucy Hale, and a Chanel-wearing Rose Byrne. Both Jonah and Liam wore Ermenegildo Zegna.

We caught a moment with Liam on the red carpet, where he opened up about his big Hunger Games press tour. He spoke about the devoted fans of the series he's encountered so far, saying, "We had our first mall event the other day, and there were lots of screaming fans, and a few teary-eyed fans, which was interesting. Very nice and very flattering to see people that passionate about it." Dakota told us she's not familiar with Liam's franchise, but she's excited to see the film. As for a daring thing she's done lately, Dakota said, "Probably starting my Spring semester at college. That was probably the most fearless thing!" Make sure to check back later today for video of our interviews with Liam, Dakota, and the other attendees on PopSugar Rush.
