Jorginho's stepdaughter didn't attend Chappell Roan's concert in Brazil after an "aggressive and intimidating" security guard allegedly accused the youngster of "harassing" the singer.

The soccer star called out the Pink Pony Club singer after a bodyguard allegedly intimidated his wife Catherine Harding and his 11-year-old stepdaughter Ada - whose dad is actor Jude Law - after the youngster sneaked a peak at her idol over breakfast at a hotel in Sao Paulo, Brazil.

And while Chappell has insisted she "didn't see" the incident and the security guard wasn't one of her "personal" bodyguards, Catherine, who is also known as Cat Cavelli, has now offered her take on the events of the day and claimed it wasn't a hotel employee who approached her table.

She said in her own Instagram video: "I didn't realise it would get this crazy. I know that Chappell has responded saying that it wasn't her security and she didn't do it.

"100 percent, this security guard was not a security guard of the hotel ... I don't know if he was her personal security guard, but he was with her. That is all I know. Did she send him to do it? Again, I don't know.

"Look, I would like to hope not, but at the same time, I think that you have a responsibility when you are a celebrity to make sure, I guess, that the people who work for you and that act on your behalf are acting on your behalf.

"Would he do that if he didn't have her authority to do so? I don't know. If he does, then, obviously, that's a big problem because then he's representing her in a way that she doesn't want to be represented."

Catherine stressed Ada "didn't do anything" other than walk close to Chappell's table to take a closer look and see if it was the singer, but when she returned and said she wasn't sure, the security guard allegedly approached them to "berate and scold" them with a "very aggressive tone."

She added: "For me, I feel like if she really didn't send him, [the security guard] overstepped a boundary because he is quite an intimidating [man]."

Catherine alleged the security guard branded Ada "badly educated" and said he was going to file a complaint, but she pointed out her daughter was used to being around people in the public eye because of her parents' work and they had the right to walk around the hotel as paying guests.

The pair were in the city to see Chappell's show at Lollapalooza Brazil as a birthday gift for Ada, but the trip was slightly "ruined" as they ultimately didn't go to the concert.

She said: "I hope [Chappell] did not know, I hope she did not send her security over to do this. I really think she is a very very talented artist we liked her a lot we came all the way to São Paulo to watch her show.

"It was her birthday present, she asked for tickets, it was a little bit ruined because we didn't go to the show last night but that's how it is.

"I hope that maybe if it wasn't her that maybe she learns not to allow the people who work for her not to treat people like this."

Catherine and her daughter did have a more positive encounter with another celebrity over the weekend, because she shared a photo of them with Someone You Loved hitmaker Lewis Capaldi.

She captioned the post: "Thank you for your kindness."
