YUNG Filly was not popular to work with as he treated crew "badly", sources claim.
It comes as the British rapper, 29, has been bailed in Australia after being accused of raping a woman in her 20s at his Perth hotel.
According to claims made by insiders to the highly reputable Popbitch media blog, the YouTuber was not a popular figure to work alongside.
And the social media star - real name Andres Felipe Valencia Barrientos - treated his crew "badly", sources say.
Police allege Barrientos raped a woman on September 28 after a show the night before.
Footage of the rapper performing at Perth's Bar1 Nightclub was posted to TikTok by the venue.

Western Australia police prosecutor Julius Depetro says there is an "extremely strong" prosecution case against Barrientos.
He claims authorities have CCTV and photo evidence which helps to prove the accusations.
Who is Yung Filly?
YUNG Filly’s rise to fame saw him start out as a social media star.
The influencer got his big break on YouTube before moving into mainstream TV.
Although he goes by Yung Filly, his real name is Andres Felipé Barrientos.
He was born on August 6, 1995, and moved to the UK from Colombia when he was two years old.
Filly then relocated to southeast London during his childhood.
When asked what it was like growing up in the capital, he told : “I come from the bottom of the barrel…and that’s why I’m so grateful for the position I’m in now.
“My mum definitely shaped me with the lessons she taught me.
“She’s a single mum with three kids, my dad was a s*** dad so she just had to make it happen.
"She did loads of cleaning jobs. My mum worked at Poundland at the time I had some mad BBC series…just getting my mum out of the position she was in was just the biggest motivation.”
Filly is best known for being a member of the comedy group known as The Wall of Comedy.
He is affiliated with fellow YouTuber Chunkz and the pair have collaborated on many videos and tracks.
Over the years, Filly has also taken part in The Sidemen's Charity Football Match, organised by members Josh Bradley, Simon Minter, Tobi Brown, KSI, Ethan Payne, Vikram Barn and Harry Lewis.
The prosecution told the court the woman's body is marked "by a history of violent acts".
Detectives from Western Australia Police's sexual assault squad charged Barrientos with four counts of sexual penetration without consent.
He is also accused of three counts of assault and one count of impeding a person's normal breathing or circulation by applying pressure to their neck.
Barrientos' defence lawyer argued the victim was drunk at the time of the alleged ordeal on September 28, Channel 9 reported.
He had performed a show at Perth's Bar1 Nightclub hours before meeting the woman making the allegations.
Prosecutor Depetro wanted Filly to remain behind bars as he accused the star's fame of potentially playing a part in the assault.
He said: "This has already made headlines.
"Given nature of social media, nature of people jumping on bandwagons, given the nature of (the) power imbalance between the parties."
In the hours after Barrientos was charged England's FA swiftly pulled him from their upcoming YouTube projects.
He was involved in a series of videos due to be part of "The Greater Game" campaign launched yesterday by the FA alongside M&S who sponsor the national side.
It has been designed to promote healthy eating and help to "positively influence" kids aged between 12 and 16 years old.
