Will Arnett and Alessandra Brawn
Will Arnett and Alessandra Brawn dated for six years.
Despite parting ways, the pair are said to be amicably co-parenting their five-year-old son, Denny.
The couple, who made their red carpet debut at the Creative Arts Emmy Awards in 2019, have not been publicly photographed together since September 2024.
In April of this year, Arnett was spotted arriving at model Gigi Hadid’s 30th birthday celebration at Le Chalet in New York, accompanied by influencer Leah McCarthy, 30.
It remains unclear whether Arnett and McCarthy attended the event as a couple or simply as friends. Arnett has long been close friends with Hadid’s boyfriend, actor Bradley Cooper.
Arnett's Family
Will Arnett is best known for his roles in 'Arrested Development' and 'Bojack Horseman'.
In addition to his young son with Brawn, Arnett shares two teenage sons, Archie, 16, and Abel, 15, with his ex-wife, comedian Amy Poehler.
Arnett and Poehler, who divorced in 2012 after nine years of marriage, have maintained a strong co-parenting relationship. Poehler even appeared on Arnett's hit podcast earlier this year, joining co-hosts Sean Hayes and Jason Bateman.
Parenting
Will Arnett and Alessandra Brawn will co-parent their 5-year-old son.
During an April episode of "SmartLess", Arnett praised Poehler's parenting approach.
He said: "I have to try really hard, but Amy, you're really good at this, and you help me do this in concert with you, to remember to listen to what they're saying and to not try to impose what I think, 'You need this, you need that.'
"To actually sit and listen to what your kid is trying to say. Encourage them to, as much as they can, to speak. I don't come by it naturally because that's not how I was raised."
