There is a new member of One Direction, and he's a puppet!
Ok, he's not officially part of the band, but in a new video from Sesame Street, Bert sang the ABCs with Liam Payne and Harry Styles.
Luckily, the boys knew the alphabet.
Towards the end of the song, they did start to mess up, but they recovered well, with Bert's help. They finished the song strong, with a lovely crescendo.
As a trio, Harry, Liam, and Bert didn't harmonize well. So I think it's safe to say Bert won't be joining the boy band as an official member anytime soon.
