Nominated for two Emmy Awards this year -- for Outstanding Lead Actress in a Comedy and Outstanding Writing for a Comedy, both for Parks and Recreation -- Poehler didn't mention her shocking split from Arnett, 42, when chatting with Ryan Seacrest. But one of her boys with Arnett -- Archie, 3, and Abel, 2 -- helped dress her for the big night. "This is a two dollar adjustable ring from my child's toy box," she told Seacrest.

Although bubbly during her chat, an insider told Us Weekly that behind the scenes, "The past few months have been rough for them . . .I don't think anyone in their circle saw this coming."

Still, Poehler and Arnett "have a lot of respect for each other," the source says.
