One Direction and "Sesame Street" have joined forces!
Back in December, 1D stopped by the "Sesame Street" set to film a special episode for the show's upcoming 45th season. To create hype around this great and powerful partnership, the kids series posted video on its YouTube channel -- the educational parody "What Makes U Useful."
Now "Sesame Street" has released another adorable teaser video. The concept is simple: Harry and Liam join Bert to sing their ABC's.
All we can say is the alphabet has never sounded so dreamy.
