So there is this stunning woman that i remember from 2014 when i went to my friend’s birthday party and she was there. I remember that we had some exchange of glances and then i asked my friend if she was available and he said that she was hooking up with a friend of his, so i did nothing. Never saw her again, but it happens that we are going to the same party next friday, do you think its a good opening to mention that ? My doubt is if she can possibly founds it weird or needy, because this was long time ago and i haven't been friends with this guy for years (due to lack of contact).

Edit: i dont think she will remember me, we were 18 years old (my face got older) and we didn't even say hello or talk... my intention in mentioning this situation would be to kind of throw in the air that she already looked at me, even if she doesn't remember it can't be a differential ?
