I admit I was a bit surprised when I saw the video.
Well, I am sure "longtime friend" had a completely different meaning for celebrities than it does for us.
Like "We met at social events, move in the same celeb circles and maybe that person has good networking connections"
And from what I saw of Yoshiki and interacting with fans I say he is too polite to say "no" when someone asks him something
We see plenty of pics of Marc Benioff with Yoshiki, That's when I would use "longtime friend" Ivanka...have we ever seen any other pics of them?
I cannot remember any.
