Perry performed for a crowd of 13,000, encouraging voters of Nevada to vote early for the upcoming presidential election this week. As for her choice... that seems pretty clear judging from her ballot box bodycon.

Here's Perry's getup for the first-ever Pepsi Billboard Summer Beats live special. A clip of the performance appeared in her 3-D concert documentary, Katy Perry: Part of Me.

Katy loves the kids! After rocking neon green head-to-toe for the Kids' Choice Awards Carpet this year, the pop star turned gladiator, replete with body armor and sword.

For her second world tour, Katy took a cue from Catwoman, rocking a sexy, slashed bodysuit. In fact, we're pretty sure this number helped Katy's tour earn wins for best live act/headliner at the MTV Europe and People's Choice Awards, and a #13 rank on Billboard's top tours of 2011.

Well hello, toy soldier! Perry got into the holiday spirit during the Z100 Jingle Ball at Madison Square Garden.

Ca-li-for-nia girls are unforgettable! And so is Katy Perry's performance of the chart topper at the 2010 MTV Movie Awards. Of course, fellow West Coaster Snoop Dogg made an apt cameo to perform his ode to girls from the golden girls.

This is just one of 10 — TEN — looks Ms. Perry pulled off at the MTV Europe Music Awards in '08. Looks like everyone wanted a piece of her and her gown.

Yes, that is Katy Perry rocking a blunt, black bob and sushi-embroidered leotard during her performance the 2009 MTV Video Music Awards in Japan. Wasabi, not included.

Katy kissed a girl and dived into a life-sized cake at the 2008 MTV Latin America awards after ripping off the bottom half of this sweet 16 gown. Caliente!

Ahh, the carousel dress! Perry made Manish Arora popular after wearing this over-the-top creation from his Spring 2009 collection for her performance at the 2008 MTV Europe Music Awards. We wonder how hard it was for her to sit down in this?!
