Will Arnett reveals 'very happy' new romance.

During the latest episode of his SmartLess podcast with guest Seth Meyers, co-host Jason Bateman asked Arnett for an "update on your love life and domestic life". "It's going really well," Arnett replied. "Both of you know exactly what's happening and I'm not going to walk into your trap. I'm very happy, very, very happy. Things are going great.". People magazine reported that the Arrested Development star is dating Emma Marciano, co-founder of Los Angeles fashion label Mimchik. Prior to his current relationship, Arnett quietly split from fashion businesswoman Alessandra Brown in late 2024. They share a six-year-old son, Denny.
