Passersby on the streets of Los Angeles were treated to a showbiz surprise this week as they ran into Christina Aguilera filming a music video her new record.
Striking with her platinum blonde and matching white outfit, the 28-year-old drew a crowd in Hollywood as she appeared to be busking in one of the takes.
Although details of her new track have been kept under wraps, the singer has hinted about material on her eagerly-anticipated fourth album, which is due for release in November.
"I can tell you that this record is all about fun," she said. "There's also going to be a modern element to it that comes from my love of Tokyo."
And it's been a busy week for mum-of-one Christina, who has been named global ambassador for the World Hunger Relief charity.
The singer hopes to "raise awareness about the issue and move people from hunger to hope."
"It is unacceptable that a child dies every six seconds somewhere around the world from hunger," she added.
