“Alexander Denison Arnett was born in Los Angeles on May 27th,” Arnett’s rep confirmed to Page Six on Friday, adding, “’Denny’ is home, and everyone is doing well.”

The “BoJack Horseman” voice actor, 50, and Brawn have been linked as a couple since May 2019.

News that the couple was expecting a child together broke in February. “They are very happy and thrilled,” an insider told Us Weekly at the time.

Denny is Arnett’s third child. He shares sons Archie, 11, and Abel, 9, with ex-wife Amy Poehler, to whom he was married from 2003 to 2016.

In 2018, Arnett gushed about parenting by saying, “There’s nothing like [being their father.] It’s the greatest thing ever. There is no other single thing in my life that is even in the same category.”
