Sky Ferreira claims her career has "stalled" because she has been branded "difficult".

The 30-year-old singer hasn't released an album since 'Night Time, My Time' in 2013, though she has been teasing the follow-up,'Masochism', for several years, but all that has materialised from her has been 2019 single 'Downhill Lullaby' and last year's 'Don't Forget'.

And now, Sky has shared a clip of a song, which dated back to 2019, and claimed she's "frustrated" about her career seemingly being on hold indefinitely.

She wrote alongside the clip: “I WANT TO PUT THIS OUT.”

She then added on her Instagram Story: “I TRIED TO PUT THIS SONG OUT FOREVER AGO. This is not my fault + it’s not a conspiracy or whatever.

“I am not a hysterical/lying/lazy lunatic. I can pull up performances from 2014 of unreleased singles too. This is beyond f***** up. I am so frustrated + over it (sic)".

Sky then claimed she has had no choice but to be "difficult", even though it hasn't been received well.

She wrote: “Being ‘difficult’ or ‘high strung’ doesn’t give people the right to damage + stall my career. I am in a DIFFICULT situation + I have to be ‘difficult’ to get through it.

“I have to protect my work + myself somehow? A lot of it is not being allowed to say or do anything I want/need without it being dismissed. The thing I actively tried to avoid happens + it somehow gets reversed.”

The 'Everything is Embarrassing' singer was just 18 when she released her first singles and she previously said she felt "trapped" as a young artist because so many people had ideas about her image.

She said: "In the music industry, everyone’s trying to mould you. They have an idea of what you should be.

“People get greedy. When I was younger, I got cornered in situations where it was like, ‘You have to do this,’ and I didn’t know better.

"It was just different back then... The internet was there, but it wasn’t this thing that people had figured out.

"I used it to my advantage – that really helped me get my stuff out. But I’ve been shelved so many times."
