Nicole Scherzinger and her band, The Pussycat Dolls, celebrated her 30th birthday with a party at LAX Nightclub on Sat. June 28. Some guys posed with Nicole but her boyfriend remained as Lewis Hamilton. Nicole had just said farewell to him in London last Friday to return to LA for her birthday party celebrations. She was dressed in a beautiful white dress and tiara. Her birthday cake was shaped in tiers and she naughtily took a bite on the chocolate slash. Happy Birthday, Nicole!
