If you do get a chance to meet Kanye, it's very likely that you won't have much time to interact with him. You may also be a little dumbstruck with the thrill of meeting an admired celebrity in person. Have a plan for what you will say and whether you will ask for anything, like an autograph or picture. If you're one of hundreds of fans waiting to talk to him, be respectful and don't take up too much time. If you happen to run into him in a public place while he's going about his business, don't be too pushy when you interact with him, as he may not be in the mood to talk to fans. It can be tempting to snap a stealth shot when you spot a celebrity, but if you want to actually talk to Kanye, don't risk irritating him by taking an unauthorized photo. The same goes for physical contact -- don't hug or touch him without asking. If you do request a photo, keep it simple and personal. For instance, you could say, "I'm a huge fan of your work. Do you think I could take a quick picture to show my friends back home?" Celebrities get approached by fans every day. If you want to tell Kanye how much you like his music, share something sincere about how much it means to you. If he wants to continue the conversation, by all means do, but you should be ready to say something concise and then leave him alone unless he wants to keep talking. Again, celebrities hear from fans all the time about how great their work is. Show how much you really care about Kanye's work by referencing something more obscure, like an album he put out before he became famous. Kanye has a long list of producing credentials from before he began his rapping career, including Jay-Z's album "The Blueprint." Kanye also has a number of philanthropic and business ventures, such as the Kanye West Foundation, which works towards improving literacy and education opportunities. Kanye is known for being unpredictable and eccentric. Don't be surprised if he doesn't act the way you would expect, or if he seems different in person than you imagined. After all, it'll make a better story that way!

Summary:
Have a plan for when you meet him. Pay attention to the situation when deciding how to act. Take pictures only with permission. Be honest and brief if you get a chance to talk to him. Compliment him on something he's not well-known for. Be ready for anything.
