In an interview with Charlamagne Tha God, Ed Sheeran revealed that his new album No. 6 Collaborations Project [to be released July 12th] was born from an idea to remake Lady Marmalade with Bruno Mars & Justin Bieber.
Apparently the whole concept came crashing down pretty quick, due to Bruno's resistance. Maybe that's a good thing, considering that the internet's reaction has not been particularly enthusiastic. LOL!
