I've kinda met Brandy but not really. I've seen her live a couple times now and the first time was during Two Eleven and we waited outside for her after the concert and I got pretty close to her and exchanged eye contact with her but I was so star struck that I couldn't say anything lol. Silent was there as well and ironically now we are friends. Also Ryan the ex was there and I can confirm that he was a bit of a douche, no shade. Well, he came off as a douche he didn't really do anything to ruin the experience of meeting Brandy lol. Anyways, the last time I saw her was during Chicago and I'm pretty sure she saw me because I was front row and she looked at me as if she knew me or had seen me before.
I've never met Gaga in person but I was front row at the ArtRave and that was pretty close to meeting her lol.
I really wish I could have met Aaliyah before she passed tbh.
