Is it okay to be friends?

I have two guy friends they are twins and are 1 year older then me , we have been friends for a while (5 years since childhood) but people has been saying that "isn't it weird that *my name* keeps hanging out with those two she is so such a pick me" and stuff like im only with them because of their looks and attention.which is not true. I always leave them alone and even keep my distances when they have girls with them to not cause misunderstandings ,i seriously see those two as my best friends who understands me and always will be there for me like family, so I'm I a pick me? And is it weird for being friends with two guy friends?
I just wanted to ask cause I'm still quite young to understand and just wanted to ask for some future advices (๑•ㅂ•)و✧
