In a new interview with MSN Music in the UK, Tedder reveals that he has begun working with Adele on the follow-up to her 2011 album, 21. An album he had a hand in, writing songs called "Rumour Has It" and "Turning Tables."

"I haven't heard everything she's done, but I've heard everything we've done and I'm as proud of it, or prouder of anything we did on the first album, and she is sounding even better than ever," Tedder said.

As for details of what the album sounds like or when it will actually come out, he's staying mum. "She will deliver the album on her own timetable, at her own pace, and the only person that will ever declare it finished will be her, when she decides it's finished," he said.
