Victoria Xipolitakis, whose 38DD curves have earned her legions of male fans, was escorted from the public gathering as she stood in the front row cheering Pope Francis dressed in dungarees and a sheer white top – with her nipples clearly on show.
Her revealing appearance was even greeted by boos from the crowds, with some yelling at her: “Out! That’s it! Come on!”
A video captures the moment she is embarrassingly led away from the scene by security guards as she holds a small child to her chest.
The controversial model is no stranger to drama and has already been involved in two other scandals this year.
Just six months ago she was accused of using Photoshop to edit an image of her derriere to make it appear curvier after she was crowned a local carnival queen.
Following their sacking, she said: “I want to apologise from the bottom of my heart to everyone.
“That was insane. I didn’t realise what I was doing and my life was also being put in danger.
“I’m not a bad person, I try to be good to people.”
Pope Francis had been in Latin America for eight days when the controversial pin-up decided to take her chance on the last day of his tour.
But is understood she did not get her private audience before Pope Francis left.
