On Saturday afternoon, reality starlet and singer Aubrey O’Day hosted the day at Liquid Pool Lounge at Aria joined by daytime revelers including her “All About Aubrey” co-stars Krystal Bronson and Rob Knox. DJ Loczi spun a special set from behind the turntables,  giving several shout-outs over the mic to fellow partygoers throughout the day. O’Day spent her afternoon hosing the crowd with Champagne during her very own “Champagne fire drill” before relaxing on a lounge chair at her VIP cabana, where she was presented with a speciality cake decorated with purple frosting and topped with a glittering microphone. O’Day spent the remainder of her afternoon mingling with her friends while continuing to soak up the sun.
