Nia Vardalosis not the possessive type when it comes to her “best friend” and on-screen husbandJohn Corbett.

In the new issue of PEOPLE, the Canadian actress, 60, opens up about filmingMy Big Fat Greek Wedding 3with the actor, who has played her boyfriend-turned-spouse Ian Miller in the franchise for more than 20 years.

Corbett, 62, also happens to have a very high-profile gig asSarah Jessica Parker’s love interest Aidan Shaw on the Max comedyAnd Just Like That…, a role he also played on the 1998-2004 hit HBO seriesSex and the City.

And even though Corbett romances both stars’ on-screen alter-egos, Vardalos says there’s no tug of war.

“This is the message to Sarah Jessica Parker: We can split him,” jokes Vardalos, who also serves as writer, executive producer and director of the thirdGreekinstallment. “I will take Mondays, Wednesdays, Fridays. We can share John Corbett.”

Vardalos sings her costar’s praises and says she knows why Emmy-winner Parker “loves” working with Corbett as well.

“The thing about John is he just looks good all the time. He’s lanky and he’s very easygoing. And he’s such a feminist that that’s so sexy,” she adds.

“Right now, this is the season of John Corbett between […And Just Like That] and our film coming out, and nobody deserves it more than this guy. He’s a good guy,” she continues.

Indeed, she says he encouraged her to direct the third movie and is a cheerleader for her career.

Gathering the cast to make the third movie on location in Greece was an emotional experience.

“The first time I had the whole cast together, I told him how I wanted to honor Michael and that I would be dedicating the film to Michael and everyone fell apart,” recalls Vardalos.

My Big Fat Greek Wedding 3premieres in theaters Friday, Sept. 8.
