Met Gala 2015: Madonna, Lady Gaga & Katy Perry (officially end their feud)...

Previously, Lady Gaga subliminally accused Katy Perry of copying her props and costumes for her tour and Perry even made some jabs at Gaga's music videos.

Madonna has never hid her views that she thinks Lady Gaga is a copycat, who has often swaggerjacked her look and sound during the 'Born This Way' era. So who'd have thought these three would have cosied up together in the same pic?
