Flanked by an army of "Sesame Street" all-stars (including Big Bird, Elmo, Grover and Cookie Monster), Will croons an inspirational track about being yourself, setting goals and working hard to achieve those goals. The video segment was recorded back in November, and MTV News was there to catch up with Will (and Grover).
"The song is called 'What I Am,' and it's about making goals and working hard to achieve them," Will told MTV News. He was especially honored to be on the set of "Sesame Street" and working with some of the Muppets who gave him his early education.
"You have to understand: I was like 4 or 5 years old, and I always wanted to watch 'Sesame Street,' " he said. "Grover helped me learn about numbers and about the alphabet, and I used to know all the songs."
He had a fan in Grover, who insisted he liked the Black Eyed Peas, as well as "carrots, broccoli, all those vegetables." Grover later taught Will a few dance moves while the producer provided beatbox backup.
Will represents the first in a series of high-profile guest appearances on the 41st season of "Sesame Street," including Katy Perry, Usher, Jude Law, Ryan Reynolds, Kara DioGuardi, Reggie Bush and Zoe Saldana.
