I was lucky enough to get invited along to go and see Lady Gaga. It was cool. She's cool. She spoke too much though. I was happy I didn't have Ehan there with me (there were a LOT of kids there!!) when she had a half naked woman riding her (she was a motorbike). It was fun but my back hates me for it today.
PS. We went there in a shuttle - drinking champagne - eating strawberries and pizza - totally recommend that!
