Allison Williams Launches First Podcast, Created with Her Lifelong Besties: ‘A Really Fun Next Chapter’ (Exclusive)

Allison Williams is entering the podcast arena!

The M3GAN actress, 37, will soon launch her first-ever podcast, alongside her lifelong best friends Hope Kremer and Jaymie Oppenheim, PEOPLE can exclusively reveal. Per an official release, Headgum’s Landlines will see the trio “open up their shame-extinguishing group chat to discuss all of the ‘what the s—?’ moments of adulthood and parenting.”

Williams tells PEOPLE that the first episode of Landlines “is truly an introduction, but from there, it goes in a bunch of different directions.” (For a sneak peek, listen here.)

“We tried to come up with a wide array of topics, wherein there’d be something for everyone,” she explains. “There are discussions that feel pretty specifically about parenting, but then there are more broad topics like aging and hormones and conflict/resolution in relationships.”

Williams — who is mom to 3-year-old son Arlo, with fiancé Alexander Dreymon — admits she still hasn’t “totally wrapped my head around being in the podcast game,” but says she first got the idea for doing one “because of a group chat I formed when I was pregnant.”

“During this stage of my life, I’ve found that I’ve leaned the most on my friends from growing up as we all navigate roughly the same things at roughly the same time,” the Girls alum continues. “And two of my friends happen to be experts in fields that I was constantly asking questions about (Jaymie is a therapist, and Hope is an early-childhood educator).”

“So I thought, what if I could give other people access to Jaymie and Hope’s expertise?” she adds. “And maybe along the way, I can share a few life lessons of my own.”

Teaming up with Kremer and Oppenheim has felt like a natural extension of their lifelong bond, as they’re “all from the same town and from very similar demographic experiences.”

“While we don’t represent a plurality of identities in that way, we’re each wired very differently emotionally,” Williams tells PEOPLE. “By discussing those nuances and our different responses to things that happen in life … we feel confident that we’ll connect to the inner wiring of our listeners.”

The experience of collaborating with her two best friends has also felt “pretty dreamy” for Williams, who explains, “The thing about knowing someone for the vast majority of your life is that their behavior in any new area is going to feel somewhat predictable.”

“Obviously there are some surprises. Like: Hope and Jaymie have spent exactly zero time in the public eye thus far in their lives,” continues the Get Out star. “But they’re so articulate, thoughtful, instinctive, and have learned so quickly about this facet of my life that has been thus far mysterious to them. And I have followed their lead at times, as I’ve been navigating how much of my own personal life to share on the show.”

Williams raves that it has “been so much fun to do something that feels so professional with” Kremer and Oppenheim, after having known each other on a personal level for so long.

“We’ve been with each other from kindergarten: playing on travel soccer teams, through having braces, going through puberty, remaining in touch through high school and college, into and out of relationships and starting families … this just feels like a really fun next chapter,” she adds.

Landlines premieres June 9, with new episodes every Monday.
