"That's my family. Those are the people that affect you the most, take up the most space naturally as a human who's born into something," she told the outlet.

"Just because you're born into a family doesn't mean that it always stays together.

"You can only control your side and your street ... I've had a very complicated life, and my parents had a very complicated thing.

"I know it's not rare, and I think it goes back to the theme of, Why share now? I guess I just felt ready."

The lyrics of We Don't Talk appear to be about her rumoured estrangement from her sister.

"People ask me how you're doing, I wanna say amazing but the truth is I don't know, what I always end up saying is how we don't talk," Duff sings.

"Not even sure what it was about. If I did something different would you feel something different? Would you at least let me hear you out?"

"'Cause we come from the same home, from the same love, a different combination but the same love."

Per Glamour, she reportedly sings on another track about her dad: "I wish I could sleep on planes, and that my father would really love me."

Haylie only recently "liked" a post about Ashley Tisdale's "toxic mum group" essay for The Cut. Hilary was rumoured to have been part of the friendship group.

Hilary has just confirmed her international tour to support her new album.

She will be heading around the US and the UK later this year and will also head to Australia.
