scream and faint.

Scream in my own mind and in the outside be like: OMG! Hi!... Wow I can't believe it, you're Lacey Mosley, aren't you? It's a pleasure to meet you... then I'll see how she reacts...and if I could... I would SSCREEEAM like a little crazy fan girl!! XDD

start crying. :P

Honestly, though I can see myself freaking out, and obviously I'd be in shock, I could probably keep it under control and talk to her normally, just with more excitement that I'd have talking to anyone else. I wouldn't want to scare her off with my spazzing out; she's still a perosn.
