Imagine that Johnny is standing in front of you. What will u tell him? Now look at his pic and tell him about your feelings for him

I'd probably say something like this:
"Johnny, it's a real honor for me to meet you. It's been my biggest dream since I was a kid and now あなた actually stand there in front of me. Even a thousand words wouldn't be enough to tell how much あなた mean to me and how much I 愛 you. If someone can be perfect, it's you. I've always been so crazy about あなた and I think I'll always be. I wish nothing but the best for あなた and your whole family."
That's what I've been planning to say if I'll meet him some day. But I don't know if i'd be even able to say anything in the real situation.:)

Assuming I don't die of shock (haha), I would probably say something like this.

"Johnny, I just want to say thank you. Thank あなた for your 映画 and wonderful characters. I 愛 them all! You're such an amazing and talented actor! And I admire how kind and humble あなた are even though あなた are such a big movie star. And you're so beautiful! WOW!! I've never seen a もっと見る beautiful man in my life!! Most of all, thank あなた for being such a hero and inspiration for me. I don't know what my life would be like without あなた in it. あなた give me so much happiness and joy. Thank あなた so much. I 愛 you, Johnny"

Then I would give him a HUUUUUGE hug and maybe a キッス if I'm lucky :D

I would say,
"Hey Johnny, we all know you're sexy, probably had it 発言しました to あなた millions of times..I would just like to say thank あなた for the joy and entertainment あなた provide for many around the world, and for being a humble realist. あなた inspire unknowingly, and are an experienced soul.

Then I would continue on to ravish him and eat his face off.
