PHOTO GALLERY: Katy Perry at the Mika Concert

Well hello there, Katy Perry! Nice to see you hanging out!

The “I Kissed a Girl” singer—who turns 25 on Sunday—seemed to be taking her fashion cues from Lindsay Lohan as she attended a concert by singer-songwriter Mika at the Hollywood Palladium on Friday night.

On her way out of the show, Perry stopped to chat and take pictures with fans, because she’s just cool like that.
