During an Instagram Live session she said it used to be "absolutely unbearable" to be compared to Miley adding that people told her, "No matter what, I was going to be in that shadow."
Miley has also spoken out about how her own fame has affected her younger sister's career.
“I think it makes you jaded, it makes you guarded, and I don’t ever want [Noah] to get like that or your style or the way that you think because you want to please people,” the "Mother's Daughter" star said on a podcast in 2017.
