When I say actual, I don't mean official, I mean that if you put on your pair of 3D GA-GLASSES then it will become 3D! I made this cover so if you use it which I REALLY encourage you to do, then please can you credit LadyGaGaUK because it took a lot of time... And talking of 3D I am working on a very amazing surprise... 5 to be precise! Check back soon :)*By the way, it may not be recorded in the O2 Arena but I am guessing it's quite likely so ;)
