One shouldn't think about others religion when you like them, doesn't matter what ever the relation it lists to, may he be a friend, neighbours, stars, lovers, etc.
Don't forget that a person is never asked in which religion do he/she want to take birth in. It's just the rules and peoples ignorance that every individual is divided into different religions. Religion is not formed by God. Don't you think God would have taught other to love and live as an equall individual and not differentiating one as lower then other. Don't think about such stuffs. Beauty lies in the people themselves, and not the religion they follow.
