Miss Pennsylvania is finally getting some backup ... because a SECOND Miss USA contestant is now saying there is PROOF the competition was rigged.

Problem is ... the corroborator is not revealing her identity.

FOXNews.com says the network spoke with the mystery contestant ... who says Miss Florida Karina Brez told her she saw a secret Miss USA document which contained the names of the Top 5 finalists ... before the Top 15 were announced.

"I saw Florida backstage and she was very, very flustered and upset. I thought it might be because she didn’t make the top 15 cut, but at that point she was able to reveal to me at least four of the five names who went on to be the top girls," the contestant told FOXNews.

The mystery woman continued, "[Miss FL] couldn’t remember the fifth because she was so upset. Several of the girls then started hearing through the grapevine about a list; a lot of people were upset.”
