Noah Cyrus appreciates all the advice she receives from big sister, Miley Crys, as her career takes off, but doesn't always take it into consideration when making her own decisions. 

ET's Carly Steel caught up with Noah on the red carpet at the premiere of Fifty Shades Darker in Los Angeles on Thursday where she seemed to take a style note from Miley in a daring black ensemble, but revealed that she doesn't always like taking her sister's advice.

"We're sisters, so I don't like taking advice from either of my sisters," shared Noah, wearing a John Galliano dress and Saint Laurent shoes. "I think I just get really cranky, especially like, getting advice from your mom. You're just like, cranky."

"I take advice from both my sisters all the time," she later admitted. "We try to help each other as much as we can without getting in the catty sister fight."

Noah is definitely all grown up. In fact, Miley's little sis revealed she's super excited for the 50 Shades of Grey sequel.

"I am [a big fan of the movie]," she confessed. "I've literally been waiting such a long time for this to come out and like, I freaked out whenever I saw the first trailer. I'm like, literally so shook right now. I'm excited."

Noah also revealed that her album is slightly more adult than people might expect.

"I'm really excited. We announced the album title last week, it's called NC-17, it was named after various reasons. The rating, it's 2017, I just turned 17, so it's just a ton of different reasons, it's really cool," she said. "I just came out with my single called 'Make Me (Cry)' featuring Labrinth and that song has been a huge blessing. The response has been incredible. It's been amazing to have Labrinth on the record."

"I'm just finishing up the album. I'm really excited. I have a lot of great people that I've been working with," she added. "I've been writing on everything and I'm really excited to work with some more producers and finish everything up."

While Noah might not like taking her sister's style advice, she's more than happy to accept a birthday party thrown in her honor. Check out the epic birthday party Miley threw for Noah and Liam Hemsworth in the video below.
