One Direction plus Sesame Street equals the most adorable ABCs rendition ever!
In a clip for their appearance, Harry and Liam sing the alphabet with Bert. The three sing from A to Z before belting out a giant finale with, "Now we know our ABCs, next time won't you sing with meee!"
Then all five guys sing their hit song "What Makes You Beautiful" with the lyrics changed into an educational lesson about the letter U.
"This letter's U, you know it's true/ it starts some words, there are more than a few," Liam sings before Louis adds, "U starts ‘uh' and ‘ugh' and ‘up'/ U starts ‘udon' there's some in this cup."
"Harry chimes in, "Twenty-six letters are in the alphabet/ but we're here to sing about U."
