Over on Twitter, tweeters are buzzing about the show, too: "Private Halloween Party I photographed last night was amazing. Christina Aguilera is a great performer. :) #photographer #SanDiego," tweeted RomanCastro.
It's not the first time the financier and his wife, Tanya, had a big name for their annual Halloween party spooktacular. Last year, Fergie, of the Black Eyed Peas, was the headliner, and the year before that, Chris Isaak performed, according to a guest invited to this year's bash.
The former Mouseketeer's paycheck for the one-hour gig this year was a whopping $1 million, TMZ reported. A few videos purporting to show the star performing at the party have popped up on the Internet, showing her belting out "Ain't No Other Man," "Dirty" and "Bionic."
The singer, decked out a black leotard with a black train and a glittery, sequined belt, can be seen onstage in the videos accompanied by a half-dozen dancers, with costumed partygoers paying rapt attention.
