britney spears demi lovato simon cowell x factor

On Saturday Britney Spears and Demi Lovato were in Oakland, California for yet another round of auditions for The X Factor, and the ladies were joined by fellow judges Simon Cowell and L.A. Reid.

Demi loved the attention, but Brit Brit seemed a bit overwhelmed! The pop star plugged up her ears and made a series of silly faces from the stage, but despite the din inside the Oracle Arena, she had a blast. "Another fun day of judging w/ @SimonCowell @ddlovato @LA_Reid," she tweeted. "The audience was so sweet! I hope tmrw's talent is ready to wow us all...."

Demi also shared her sentiments on the microblogging site, but she seems more interested in herself than the contestants! Demi tweeted this shot and wrote, "Loving my pink hair and obsessed with my new Topshop outfit and Chloe Green shoes!!!!"
