Leighton Meester has joined the cast of 'Nobody Wants This'

Leighton will portray Abby, a social media mommy influencer, who was the middle school nemesis of Joanne (Bell) and crosses paths with her as an adult.

In addition, Miles Fowler will also make a guest appearance on the show as Lenny, a Matzah Ballers teammate of Noah (Brody) who gets set up with Morgan (Justine Lupe).

Adam recently revealed he and Leighton - who have two children together - act as "each other's managers" and don't take on new roles without discussing the projects with one another.

He told Dax Shepard's 'Armchair Expert' podcast: "Everything is run through each other.

"We are each other's managers, and we also have the same two agents... We are in each other's s*** in that way, and we even did a movie together a couple of years ago."

The pair - who met on the set of the 2011 rom-com 'The Oranges' and got married in 2014 - have starred alongside each other a handful of times, including the 2023 thriller 'River Wild', 2014 rom-com 'Life Partners' and sitcom 'Single Parents'.

Adam, 45, explained that the 38-year-old actress is very much all about the "art" and hailed her a "poet" for the "depth" she brings to the roles she takes on.

He went on: "She's charmingly aloof to the business. She will literally not know Seth Rogen's name, you know what I mean? ... It's f****** great, because it doesn't diminish her art.

"That's not where she's focusing, and so she has that outsider quality, and she can come in, but she's such an artist.

"She's a poet, she has a depth and a read on material that is always illuminating and has a great radar.

"And so she can still get at the heart of something, a script, no problem, but it's for me to look at the cover letter and go, 'You're doing this or not.'"

Leighton judges a project by its script and not if it has big stars attached to it, but Adam will always encourage her to take a part with notable names.

He added: "Before we even have read it, I'm like, 'Oh, these names, these are good names. You probably want to be involved.

"'I haven't heard of these names. Sounds sketchy. Give it a read. I'm the biz guy.' But she knows from an intelligent, intuitive way what's true and what's lyrical and what's bull****."
