I'm not even sure...
The chances that I would actually meet her would be very slim.
I did tear up when she came really close to where my friend and I were standing.

For a second I swear we made eye contact.
Edit: I'm an idiot. I answered about Britney.
If I met Gaga I would lose my **** cause she is so uber-famous, but I'd try and play it cool so that I could at least get an autograph out of it and not totally scare her away.
