I'm pretty famous for acting, Facebook, and being in videos (maybe not as famous as you, but... Whatever).
I handle it by being very friendly, but selective. I don't take flattery well for the most part..

It feels cool to get complimented. I reacted to compliments by becoming very friendly and a little over-eager instead of maybe qualifying. Now I kind of lay back, and just let them approach me... Always being friendly and perhaps a little elusive because I need to do something else. Or I'm just not that interested in them... Unless I want to get to know them, then I start talking. I've had multiple girls hitting on me, one was with their boyfriend too. I just let them all do it being social, paying the most attention to the ones I wanted the most which I was giving a back-hug to, and flirting with another. The others were left with watching me do this, and talking shortly afterwards. Well... Except for the girl I was back-hugging - she just kept doing it while I talked with everyone.
Another time I remember was right after a performance and I kept getting compliments left and right, well I just went with my instincts and briefly flirted with all of them while I tried to get my head straight.
Now that I think of it being known is kind of creepy... Especially one girl. She's cute, but I don't really like her and she's one of my best friends older sister (they're not very close) and she comes on a little strong. She's always staring at me, and creeping me out by copying me, feeling me, talking about sex out of nowhere... Fun, but I just play hard to get and always give her the cold shoulder - this has just kept it coming thus far. Her friends have taken notice and started getting interested, which is good because they're cute. I don't really like hanging out with their social circle because they're a bunch of stoners... But I guess I could hang out with them if I wanted to go to parties. Might as well.
She's single and obviously wants me. Do you think I should cave and make a move?
That's for another time...
Being social. It just depends on the situation. If I'm talking to a girl and we're alone at first, then a crowd comes - then I just keep talking to the girl, and bring up that we must be so cool and popular that we drew in a crowd. I also get stuck in a room for 15 minutes with the creepy girls, her friends, and her brother - along with other random people. I just become the center of attention, and try to act like I'm comfortable being whispered about and stared at by a few people... I think next time they whisper I'm just going to interrupt them. If I'm getting stared at, then I usually whip out something which (maybe?) would get classified as CF. I yell out, "What!?" or, "What the fuck do you keep looking at?!" if they keep doing it... I've also handled this by having a little staring contest, but it goes nowhere - and I didn't want to start looking at her with bedroom eyes because I felt uncomfortable and felt like it might get a little awkward. There are situations, like at lunch where you get to do whatever you want - people are doing whatever, it doesn't matter... Do what you want. Do you want to talk to your friends, or talk to some newly made friends? Both are fine choices. Classroom. Well I talk to the surrounding people, and the teacher mostly. If I get to walk around the room, then I talk to different groups of people, and my friends.
Being Friendly. I open the door for people, and smile when we exchange glances. I say , "Hi" or something if I want to talk some more. It seems more of a big deal if you actually say hi instead of just walking by... Like you're becoming friends, or you're interested in each other. This varies in how long the effects lasts... I don't think you have anything to worry about since you're always performing.
Being Unfriendly. Well... This is just a little ball-busting, and playing hard-to-get. If I genuinely don't like the person, then I'll take it up with them.
Social Groups. I like consistency, so I hang out with my best friends more than anybody else. Once in a while we can't do that for some reason, then I'm off doing whatever, or chatting up some other friends or a cute girl. The other situations in Being Social could be put in this section as well.
That's basically it for me... You should just start analyzing your situation, then break new ground for the famous high school kids who still wants to be more popular and get girls. I had Liam Chang from Canadian Idol in my school, he's pretty well-known. He was pretty popular, but he hung out with who he wanted and was super cool with everyone. Friendly guy, high energy, and sung well. His sister also had a crush on me last year... I think she also has a crush on me now

Looks at me funny, gets kind of nervous, volunteered me for something and complimented me, and grabbed me and felt my abs out of nowhere.
Damn I talk a lot... Always with a big post. And more often than not, I end up giving a field report in some way.

Do you think it's a good thing? I'm not sure how I come off...
By always being friendly and selectively social you don't really run the risk of a bad reputation because you're hanging out with people you want to and people don't have a reason not to like you... Unless you're tooo friendly, then they might start getting suspicious

All I can say is that once I started trying to being friendly to almost EVERYONE my popularity started to take off. Even people who previously didn't like me are starting to now.
Good luck, man. Hope you find your way
Warm Regards,
