A review in the Philippine Star
, which first reported Perry's "torrid flirting" with Dorschner during her show, states: "After scanning the crowd and telling the men in the audience to strip off their shirts if they wanted to come up onstage with her, she finally chose the chiselled (sic) Dorschner to give her a taste of the Philippines."
Dorschner, 21, is a television host who appeared on the teen edition of the Philippine version of Big Brother
The paper went on to describe his encounter with Perry, 27, as "a raunchy segment … in a generally for-adults-only show."
