I Need Help With My 14th Bday

I need help. I`m not exactly the coolest girl in school and for my birthday i am having a sleepover with 11 of my friends, all who are girls. Well then one of my guy friends said that he is coming and he is really popular he said he will bring a couple of his cool friends. I`m afraid that they will think my party is lame what games should i play at my party for boys and girls.
