My long lost friend is now a famous rockstar.?

[noisyfog660]

I know it's hard to believe, but i met a boy a long long time ago when I was on vacation, and when I left we lost contact. Then not long ago, I have seen a music video and I realized that the lead singer looks really much like him and when a googled the singer, by the looks and the biography, he looked just like my long lost friend so I'm almost sure it's him. I haven't got his email address, but I found him on twitter. How can I make sure he responds because "hey man, we used to be good friends" sounds like a screaming fan girl trying to meet him. I'm not a screaming fan girl, I just want to keep contact. Please help. What kind of message should I send? And it's twitter so I can't send a direct message, it has to be a tweet.
