Advice

So I have a party coming up and there's going to be two people going that have both fingered me, and they are friends. Boy2 knows about his Friend, boy1 and me but i don't think boy1 knows about me and boy2. Any way I have a feeling that I'm going to be really anxious about the party and really awkward around them. I need some adivce like i have a feeling that they are both going to snob me so should I try to avoid them or should I go up to them and play it cool and have a convo? What would you do in my situation ?
