Adele will deliver her next album "at her own pace."
The 'Skyfall' singer, who is recording the follow-up to her chart-conquering album '21', has worked with OneRepublic's Ryan Tedder on new tracks and he claims she is not rushing the release.
He told MSN Music: "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.
"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."
The 25-year-old singer had to cancel tour dates in 2011 to undergo throat surgery and later took time out after giving birth to her son Angelo in 2012, with boyfriend Simon Konecki.
Asked about rumours she's nervous to perform live again, Ryan replied: "I personally wouldn't use the word fear, from conversations I've had with her. I don't think she has a fear of it.
"She's a mother, she has a young kid. When you sell 30 million albums, on one album, she can do whatever the hell she wants to do until forever."
Talking about reports of a possible world tour, Ryan also said: "If she decided to tour I'm sure it will be the most incredible tour ever and if she decides not to, it will have no bearing on how amazing the album itself is because she's one in a million, one in a hundred million, one in a billion."
