One source claims the 18-year-old was actually bullied for being there -- apparently not everyone thought she earned the right to walk the shows!
The insider spilled:
Katy Perry is the only woman who can look this sexy with blue hair!!
Partying with Elton John at his WeHo Oscar party, Katy looks fabulous in her Blumarine dress.
And she's dancing in Miu Miu pumps with her Diamond in the Rough jewels janglin!
We hope you have a blast, beautiful!!
