Katy Perry repped Team Obama in the best way she knows how - by wearing a latex dress.
Perry opened up for President Barack Obama at a 10,000 person strong rally in Las Vegas on Wednesday, Oct. 24.
The "Part of Me" singer wore a skintight white latex dress with a design that resembled a ticket ballot. The design featured two boxes on her right hip that appeared as if the Democratic ballot ticket was checked off.
President Obama and Vice President Joe Biden's name was checked and GOP presidential candidate Mitt Romney's name below it was unchecked.
Perry gave a free concert in the downtown area of Las Vegas to screaming fans at about 9 p.m. President Obama had just touched down in Sin City in Air Force One at the same time.
Perry sang Al Green's "Let's Stay Together," and her recent hits "Part of Me," "Teenage Dream," "Wide Awake" and "Firework" for her 30-minute performance.
"Don't wait. Go tomorrow," she said. "How many of you are 18 here? It's going to be your first time, right?"
When Obama arrived at the event, he addressed the 10,000 plus cheering crowd: "I believe in you. I need you to keep believing in me."
"We are pulling an all-nighter. No sleep," Obama told the crowd at an event Wednesday night. "And if you're not going to sleep you might as well be in Vegas."
The event took place not long after Obama taped an appearance on "The Tonight Show with Jay Leno," where he poked fun at Donald Trump for his "deal."
"We had constant run-ins on the soccer field. He wasn't very good and resented it," Obama joked. "When we finally moved to America, I thought it would be over."
