In the new comedy Fun Mom Dinner, Molly Shannon plays Jamie, a divorcee, who upon reentering the singles scene, turns to dating apps and Instagram in hopes that prince charming will slide ever so discretely into her DMs. (“You’re not just a mom—you’re a hot single lady,” she hilariously chants to herself in between selfies.)

In real life, of course, Shannon is happily married to artist Fritz Chestnut, with two kids of her own (Stella, 13, and Nolan, 12). And her Instagram game? It’s much more on point than Jamie’s, thanks in large part to a former Jo Bro.

Nick Jonas actually signed me up for Instagram last year,” Shannon tells InStyle. “It’s funny, I met him at a bar at the Sundance Film Festival, and after we took a picture together, he said ‘You should really post that.’ I was like, ‘Well, I would, but I don’t have Instagram.’ So, he signed me up right then and there at the bar! Now we both follow each other—and we also have the same birthday—so there’s this cosmic, social media connection. And I really like Instagram now. It’s fun!”

Also fun? Getting to pal around with the amazing ensemble cast for the film, which co-stars Toni Collette, Bridget Everett, and Katie Aselton as a group of moms who get together for a girl’s night gone awry. Paul Rudd, Adam Scott, Paul Rust, and Adam Levine make memorable cameos too.

“What I like about this story is that it’s funny but still relatable,” says Shannon, of the script that was written by Julie Rudd (who is married to Paul Rudd). “Julie put a little part of herself in all of the characters, so it comes from a really authentic place. I think all women like to see themselves and their friends represented onscreen. I know I do.”

For Shannon, who rose to fame on Saturday Night Live in the '90s, playing everyone from Anna Nicole Smith to “Superstar” Mary Katherine Gallagher, her character in Fun Mom Dinner was a still a bit of a stretch. “Jamie’s going through a transition because she’s newly divorced and is ready for her chapter two,” says Shannon. “But then she smokes a little too much pot and doesn’t have a great reaction. She becomes super paranoid, which, for me, was really funny to play.”

The actress is also gearing up for a busy few months with Wet Hot American Summer: 10 Years Later now streaming on Netflix and the second season of Divorce on HBO coming back this fall. She’s also working on a pilot for Comedy Central with SNL head writers Chris Kelly and Sarah Schneider.

So we had to ask: If Shannon could bring back any of her SNL alter egos, which would it be?

“I don’t miss doing Mary Katherine Gallagher because it was so physically hard. I don’t know if I could do that stuff anymore,” she says. “But I still love Jeannie Darcy, the bad stand-up comic that I did. You know, the one that’s like, ‘Don’t get me started, don’t even get me started.’ It’s still pretty funny after all these years.”

Fun Mom Dinner is in theaters now.
