The pair made their red carpet debut but didn't pose for photos together.
Jenny Slate officially has a case of the butterflies, and it's adorable.
The 32-year-old actress was accompanied by her boyfriend, Chris Evans, to the premiere of her animated film, The Secret Life of Pets, at the Lincoln Center in New York City on Saturday. The event marks their red carpet -- or in this case, green carpet -- debut as a couple.

Though the two didn't pose for photos together outside, they did take an adorable snap inside the theater. Slate rocked a gorgeous red lace dress, while Evans looked casual but oh-so-handsome in a polo shirt, black pants, and navy blue baseball cap.
ET's Jennifer Peros spoke to Slate on the green carpet, where she couldn't stop gushing over her hot new arm candy.
"I haven't really had a large premiere before, so it's nice to have someone who knows how it goes," she told ET.
Slate and Evans are both from Massachusetts, and she adorably noted that "it's kind of like I got my dream 7th grade boyfriend."
"We didn't know each other growing up, but we grew up about half an hour away from each other," she added, flashing a smile. "We've been friends for a while, and, yeah."

In addition to Evans, Slate invited her sister, Abby, as well as her nieces and nephews, Maddie, Sam, and Ruby, plus quite a few people from the 34-year-old actor's posse, including his friend, mother, sister, and two of his sister's kids.
"If I'm not the best aunt in America, then I don't know what's going on… I'm pretty sure I scored on this one," she joked.
The Parks and Recreation star later took to Instagram to share a video of her and some of the kids in the car ride over to the premiere, captioning it, "We do chill very hard on the way to The Secret Life of Pets. We do."

Slate voices Gidget, a "50% fluff, 110% tough" dog in the 3-D comedy, which she describes as "so sweet and so funny." "It makes me really, really happy to be in [it]," she told ET, noting that working on the film, which hits theaters July 8, was "a beautiful challenge."
She also explained that she took the role very seriously, right down to her work attire. "People say that the best part about doing animation is that you don't have to dress up to go to work, but I don't believe that," she explained. "I dress up to go to work. I dress up for an airplane. I think it's just focusing your skillset, focusing on your voice and the comedy."
When she's not on set or hanging out with her Captain America: Civil War boyfriend, Slate says she lives a fairly laidback and relaxing lifestyle, joking that she picks "a lot of flowers," while revealing a new project that she's been working on.
I've been writing a book with my dad," she said. "It's about the house that we grew up in. My sisters and I. I have a happy life. I chill out."
