Chappell Roan gave a shoutout to her security team, hours after Jorginho called out the pop star for allegedly sending a guard to accuse his young daughter of harassment, which he said left the child “in tears.”

On Saturday, March 21, the professional soccer player, 34, alleged in a lengthy Instagram Stories post, shared in both Portuguese and English, that Roan, 28, sent a security guard to accuse his 11-year-old daughter of disrespecting and harassing the musician while they all dined at the same hotel in São Paulo.

Performing at Lollapalooza Brazil later that same night, Roan thanked her security team while onstage, as seen in fan footage shared online.

Highlighting that the performance was one of many recently, the “Pink Pony Club” singer told attendees, “I do not know when I’ll be going on tour again, so this is the last one. I’m so grateful it’s here.”

“I’m so grateful, so thank you, and thank you to my crew and my security and my band, and everyone behind the scenes,” the Grammy Award winner added. “This takes a lot of people, so thank you.”

In Jorginho’s Instagram Stories post directed at Roan, he wrote, “I went through a very upsetting situation with my family earlier today.”

“My wife [Catherine Harding, who also goes by Cat Cavelli] is in São Paulo for Lollapalooza Brazil. This morning, my daughter woke up incredibly excited. She even made a sign because she was so happy to see an artist she really admires, or used to admire,” he continued, referring to Roan, ahead of her Lollapalooza Brazil set.

“By coincidence, they’re staying at the same hotel as this artist. During breakfast, the artist walked past their table. My daughter, like any child, recognized her, got excited, and just wanted to make sure it was really her,” Jorginho then wrote of the alleged interaction, highlighting, “The worst part is she didn’t even approach her. She simply walked past the singer’s table, looked to confirm it was her, smiled, and went back to sit with her mum. She didn’t say anything, didn’t ask for anything.”

After his daughter walked by, Jorginho alleged in the post, “A large security guard came over to their table while they were still having breakfast and began speaking in an extremely aggressive manner to both my wife and my daughter, saying that she shouldn’t allow my daughter to ‘disrespect’ or ‘harass’ other people.”

“Honestly, I don’t know at what point simply walking past a table and looking to see if someone is there can be considered harassment,” the soccer pro continued, then claiming that the security guard “even said he would file a complaint against them with the hotel, while my 11-year-old daughter was sitting there in tears.”

“My daughter was extremely shaken and cried a lot,” Jorginho, born Jorge Luiz Frello Filho, added.

The pro athlete did not name the child, but appeared to be referring to 11-year-old Ada Law, whom Harding welcomed with her ex, Jude Law. (Harding posted a photo of Ada smiling at a dining table at a São Paulo hotel, the Palácio Tangará, less than 24 hours earlier.)

Continuing his Instagram Stories post, Jorginho said, “It’s sad to see this kind of treatment coming from those who should understand the importance of fans.”

“At the end of the day, they are the ones who build all of this,” the athlete continued. “I sincerely hope this serves as a moment of reflection. No one should have to go through this, especially not a child.”

He then tagged Roan’s Instagram account and wrote a message in all-caps: “WITHOUT YOUR FANS, YOU WOULD BE NOTHING. AND TO THE FANS, SHE DOES NOT DESERVE YOUR AFFECTION.”

Roan — who has since spoken out about the situation — has long been an outspoken advocate for boundaries between herself and fans, as well as paparazzi.

Earlier this month, she made headlines for calling out a group of photographers and admirers who waited outside the restaurant where she was dining for “harassing” her.

Lollapalooza Brazil is taking place between March 20 and March 22 at the Autódromo de Interlagos in São Paulo.

Other performers include Cypress Hill, Katseye, Lola Young and Marina, among others.

Representatives for Roan and the Palácio Tangará have not responded to PEOPLE’s requests for comment.
