How did Pussycat Dolls singer Nicole Scherzinger warm up her gig opening for Britney Spears
on the Circus tour? She was maid of honor at her sister's Hawaiian wedding.
Heading to the Hickam Air Force Base in Honolulu for the Feb. 28 nuptials, Scherzinger sported a strapless satin and chiffon Enzoani dress as her sister, Keala Leemon, got married at sunset.
Following the ceremony, guests ate lobster, steak and red velvet wedding cake. Scherzinger also performed for her sister's first dance, as her boyfriend Lewis Hamilton looked on.
Then, Scherzinger flew to New Orleans where she met up with her band, who will open the entirety of Spears's Circus tour, which kicks off Tuesday at the New Orleans Arena. – Brian Orloff
