Ryan Tedder, vocalista dos One Republic e escritor de músicas de sucesso para Beyoncé, Leona Lewis, Kelly Clarkson, etc, está a colaborar com Adele. A colaboração é para o 2º álbum de Adele. Tedder diz que está a deixar que o trabalho transpareça mais Adele (tipo 90% ela e 10% ele) pois ele adora o que ela faz e fez com o seu álbum de estreia, 19.

Ryan Tedder, lead singer of One Republic and responsible for hits of Beyoncé, Leona Lewis, Kelly Clarkson, etc, is working with Adele on her sophomore album. Tedder says she's one of his favourite artists. He said: "I'm letting Adele be Adele. 19, that album was so absolutely mind-blowing to me, so simple and beautiful that I don't want myself as a fan to interfere with her sound. Yesterday the song we did was very much Adele - it was 10% Ryan, 90% Adele. "I don't want to put you through the Ryan Tedder machine where you end up with a song that sounds as much like Ryan Tedder as it does Adele."
