Well here it is! Lady Gaga apparently likes the pony. That or she is being forced into wearing ponies by the same people that make her dress up in insane costumes all the time.
I see a bunch of severed heads for the g3.5 stuff. Hopefully this is a sign of her true g4 bronydom with that awesome Rarity hangin out.
Also more information! (New!)
Anyway, another image is after the break!
