Anyone can have twins, you don't have to have a relative that had twins for you to have twins.
if you have a relative who had twins or is a twin, you have way more possibilities than anyone else to have twins, it's actually kinda genetic, but true that people who don't have any twins in their family or relatives who are twins, can have twins too, but it's less possible, less, but still.
I've tried DMing some of the followers of @/haiilie_scott on Instagram to tell them that that account is fake but most of them don't believe me.
They should realize she's fake, her english isn't perfect, no one from the family and friends follows her, especially Eminem's brother and Hailie's sisters, if she would be real, they all would follow her ( like they do on her real account ), it's quite a good proof she's fake.... But unfortunatly some people want to get in touch with her too much that they don't realize someone who fakes her makes fun of them...
