The actress grew close to the mystery super fan after they swapped numbers and began chatting over the phone.
Miley was so impressed with her knowledge that she has now hired the follower as her personal assistant and is jetting her out to Los Angeles to live with her mum Tish for the summer.
Miley said on US chat show Jimmy Kimmel Live: "Yeah, she is actually flying out here and staying with my mom this summer, she is going to work for me for the summer."
And when asked why she had decided to give the fan a job the singer made it clear it was down to her impressive knowledge.
She added: "Because, let me tell you, I never know... I don't know if this is how it works for you, but no-one ever tells me anything, I'm the last to know everything.
"I didn't know about a schedule today, I didn't know what time I was going to be here, I didn't even know I was going to sit on this couch and talk to you, I thought we were going to just do everything outside."
And Miley paid her new employee a compliment - kind of - by branding her "more than a stalker."
She continued: "She's more than a stalker because she's so obsessed, she knows things about how to break VEVO records, which we did with her help.
"She just knows... I don't know anything, I don't YouTube or whatever, so she knows what has to be done in what amount of time to be number one or to break the record.
She just knows everything."
While she was wary at first it seems Miley soon overcame her fears and formed a firm friendship with the girl.
She explained: "When I first called her, I called her off my friends phone but then I ended up just texting her all the time.
I bet she gets more annoyed with me than I get of her because I just hit her up all the time.
"I'm like, 'Yo, you gotta make this happen', 'You gotta make the fans trend this'. She's really amazing."
