Chappell Roan has developed a reputation as 'the most difficult' celebrity in Hollywood, following a number of diva outbursts and a series of public spats, according to an insider.

This week, the controversial pop star, 28, found herself in hot water once again after one of her security guard's was accused of making actor Jude Law's daughter, 11-year-old Ada, cry.

Roan has denied having any knowledge of an interaction between her staff and Ada Law, who was staying with her mother Catherine Harding and stepfather, Brazilian soccer star Jorginho Frello, at the same hotel as the Grammy winner in São Paulo.

'She did not direct her personal security or anyone on her team to interact with them,' Roan's spokesperson has said.

But following the incident, a source told the Daily Mail that some of those who work closely with the singer 'would like her to be nicer before it is too late.' 

'Her attitude isn't the best. Some would call it being a diva, others would just call it being a [expletive]. It's a shame, because she is incredibly talented, and for her to ruin what she has made for herself would be such a disappointment,' the source said. 

'[Those close to her] are hoping that she'll actually take this as a learning lesson and be nicer in the future.'

The Daily Mail has contacted representatives for Roan for comment. 

The Missouri native has developed something of a reputation for difficult behavior.

At the MTV VMAs back in September 2024, Roan - then a breakout star thanks to the meteoric success of her album The Rise and Fall of a Midwest Princess - memorably clashed with a photographer, who had been heard shouting, 'shut the [expletive] up.'

Roan, on the red carpet, turned and snapped back: 'You shut the [expletive] up! No. Not me, [expletive]!' 

A month later, at the Los Angeles premiere of singer Olivia Rodrigo's Guts World Tour movie, Roan confronted another photographer, accusing him of mistreating her at a previous event.

'You were so disrespectful to me at the Grammys. You yelled at me at a Grammy party,' she said. 'You were so rude to me... You need to apologize to me.'

From there, things have only worsened, with clips regularly going viral of the star calling out fans or paparazzi for 'harassing' or even 'stalking' her.

So much so that, earlier this month, singer Boy George weighed in, penning a public message to Roan to 'cheer up girl.'

'Own your fame,' George wrote, 'the world is at your feet stop kicking it!'

On Saturday, soccer star Jorginho Frello claimed on Instagram that his stepdaughter Ada had been left 'extremely shaken' when the singer's bodyguard had confronted the her and her mother after the 11-year-old had walked past Roan's table at breakfast, at the Brazil hotel they were all staying at.

The Daily Mail has since unmasked the bodyguard as Pascal Duvier, the same security aide who was fired by Kim Kardashian after she was robbed in Paris in 2016.

Amid a huge backlash, the singer responded in a video insisting she did not ask anyone to approach the child.

However, for some, the apology has been hard to swallow.

'We all know the saying, fool me once, shame on you; fool me twice, shame on me. And that is where we are with Chappell. Many have been fooled by her past behavior,' an insider said.

'Her problem now is that someone actually called her on her [expletive], called her out on the behavior she has gotten away with for so long. It would be best for her to take responsibility instead of digging more of a hole for herself.

'She had that incident with the red-carpet photographer at the VMAs along with other photographer issues, in which she was in the wrong. She's called out fans and now this security [guard] incident. It is a bad look.' 

In perhaps the most brutal swipe of all, the insider also warned that, without another hit song, Roan could 'be forgotten and nobody will care.'  

Speaking on the Call Her Daddy podcast last year, Roan mused: 'I think people are scared of me. I think I made a big enough deal about not talking to me that people do not talk to me.

'I've been with friends who are artists and when they're with me, they're like, "It's a forcefield around us. People don't come up to me if I'm with you."

'I'm just like, "Damn, baby, you say it too." You say, "Don't touch me, don't look at me, don't talk to me, I don't know who you are..." and they won't come to bother you.'
