Well, I don't think so, because there are too many people who are afraid of accidents. There is a precedent for a star to shake hands with his fans and be pulled down and trampled to death, but you can go up to send flowers or small gifts and ask him to sign them. There is such a precedent, for example, after the concert, you can go backstage and ask him for an autograph. This is safe and has a high success rate.
