I'd say, " Thank you, thank you SO much!!! I amor you with all my coração and soul!!! You are the only reason I'm alive and the reason I want to follow my dreams!!! You are my IDOL!!! Thank you for being alive and not conforming for anyone else because YOU WERE BORN THAT WAY!!!"
Or at least I'd try to, through my tears of pure joy and amor for her.
The first thing I'd say would be "thank you for making music" because I think my life is better since I have her music. Then I'd tell her I amor her SO SO much and that she's my idol. And then I cry and cry. I'd tell her that she is one of the very few persons that inspires me and that she means everything to me. All this is what I think I'd want to say but if I really had her in front of me I'd be speechless... not able to think straight...
I will scream liek a little girl: "AAAAAAAAAAA GAGA!!!! I amor You!!! You are Great singer!!!! Your música is so cool!!! I amor all of them!!! OMG!!! Thank you for YOU!!! " ))))))))))))) XD
idk what i would say, i would either 1. faint 2. stand there like an idiot 3. scream and yell and literally make my bff's ears bleed. 4. probly tell her that she is the reason i amor música and amor to sing. that she is my influence to become a pop estrela just like her :) i luv Mama!
