Arnett spotted alone

A fan spotted Will Arnett walking alone, probably coming back from picking up his mail at the end of his several mile long driveway, on the afternoon of January 8, 2026. Was he all alone? “Definitely yes,” says the fan, adding that “He was wearing a large sweater and looked really cute!”

Is Will back on the market?

A rep for Will Arnett was not immediately available for comment.

Truth or rumor, when news that the actor - known for having been romantically involved with Amy Poehler - was splitting hit the internet Friday (January 9), Twitter immediately exploded with pithy commentary. It seems everyone had an opinion on the matter:

“Has anyone Will’s phone number?”

“So very sad… Those 2 were so great as a couple. So cute together.”

Based on the facts (Arnett spotted alone with a cute sweater), is there trouble in paradise or is it much ado about nothing?
