That's a weird timeline...

In 2010, it was reported that Perry and Rose went out in Melbourne on the night of 6 August, including to Spice Market.

Perry “crashed” the Melbourne high school formal at the Grand Hyatt – where Spice Market was located – according to the story.

So Rose would have been mid-20s... And not an actor yet. I think she was modeling?

They ended up at a highschool prom.

Rose said Perry assaulted her, but there's the child abuse department involved.

So if Rose didn't go to the prom, it sounds like Perry tried something, got shutdown, and went a prom to pick up someone else? Like, I don't know why that department is involved if no part of the story involves a minor....

Well that would certainly explain how she was able to tolerate Russell Brand.

Katy Perry is a talentless hack and a complete phony so I'm rooting against her on this. Mostly because she's a really gross person who has a history of not respecting people's boundaries.

Is she the one that pulled a male back up dancers pants down at the front so her and her friend could try to see his penis?

I think it was either her or Pink.

Edit: it was Katy Perry:
