Prepping her performance for President Obama?s rally, Katy Perry belted out her tunes in Las Vegas, NV on Wednesday (October 24).
The ?California Girl? songstress opted for a casual ensemble in a white tank top and grey sweatpants, while on stage for afternoon rehearsal.
Eager to be a part of the event, Katy tweeted, ?VEGAS! I'm performing for @BarackObama again WEDNESDAY! Celebrate getting your early vote on & get free tix here: http://ofa.bo/BlockParty.?
The ?America Forward? rally will take place at Sin City?s Doolittle Park, and marks Perry's second appearance in support of Obama.
As previously reported by GossipCenter, the 27-year-old previously performed at an L.A. fundraiser earlier this month, with Stevie Wonder, Jon Bon Jovi, and Jennifer Hudson.
