Zooey Deschanel will sing three songs from the new Winnie the Pooh movie hitting theaters this summer.

She is one half of the band She & Him and together with bandmate M. Ward, she will sing a take on the classic "Winnie the Pooh" theme song, "A Very Important Thing to Do," and "So Long."

Deschanel wrote "So Long" and it will appear during the end-credits.

“This has been one of the most fun experiences I’ve ever had,” says Deschanel. “And I’ve just been thanking my lucky stars that I was able to work on this movie, because it’s delightful."

Director Don Hall loves Deschanel, saying: “She was the perfect choice to do the ‘Winnie the Pooh’ song—a classic theme from the Sherman Brothers. Her music actually embodies the underlying spirit of the movie. We’re taking something that has vintage roots in the sixties, but spinning it in our own way and updating it."
