Amelia’s Facebook page has some strict privacy restrictions, and her own modeling Instagram account is set to private. As for Chuck’s Facebook page, he only has the public figure page open, which is mainly photos of his racing exploits. Amelia’s FB account does say she’s in a relationship, though.
Maybe they’d rather keep their personal life a little more, I don’t know, personal and away from prying eyes? It doesn’t change the fact that the two are hella good at this whole drag racing thing.
