According to the Daily Mirror Robbie Williams is back in the studio recording and writing new tracks with the rest of Take That. Apparently Robbie met up with the rest of the band in New York for Mark Owen's stag night and from there they decided to work on some new songs.
However, a source told the news paper that “Robbie wouldn't be happy performing old Take That songs that he has had no part in. But if they can pen new tracks that they're all happy with, they'll record them and he will be back with them on stage.” Glad to see his ego isn't getting in the way of things then.
Although, you shouldn't believe everything you read as a spokesman for Take That told MSN that he could not confirm the story at this time. So who knows?
