Back in the September 8th newsletter, Deuxmoi exclusively reported that actor and comedian Will Arnett was allegedly dating Emma Marciano, a member of the family behind fashion brand Guess.
According to a source with firsthand knowledge, Arnett and Marciano had been quietly seeing each other since at least the beginning of the summer. The pair allegedly attended a wedding abroad together, with Marciano bringing Arnett as her date. The source also pointed to a photo Marciano posted to Instagram that allegedly showed the couple together from behind.
Now, Arnett appears to have confirmed one important part of that report: he’s very much in a relationship.
During a recent episode of his “SmartLess” podcast, Arnett spoke about being in a “very happy relationship.” He did not publicly identify his girlfriend, but the comment immediately raised questions about whether the mystery woman could be Marciano.
The relationship would follow Arnett’s split from supermodel Carolyn Murphy. The two began dating in 2025 and made several public appearances together, including at the 2026 Golden Globes, before reports surfaced in April that they had quietly split several months earlier.
Before Murphy, Arnett was in a long-term relationship with Alessandra Brawn, with whom he shares a son. Alessandra is now in a relationship with Emily Ratajkowski's ex-husband, film producer Sebastian Bear-McClard, with whom she shares a child. Arnett was previously married to actress and comedian Amy Poehler, and the former couple share two sons.
Neither Arnett nor Marciano has publicly confirmed they’re dating, but between Deuxmoi’s original reporting and Arnett now confirming he’s happily coupled up, the pieces certainly appear to be lining up.
