The pop princess was all smiles on Tuesday (3 September) as she headed to retail and dining complex Country Mart, but came prepared as she switched outfits.
The 'Toxic' signer wore a yellow vest top and loose-fitting black jogging pants with the word 'Love' emblazoned down one leg.
But as the hot temperatures settled in, Britney changed outfits, showing off her pins in grey shorts. She finished her look with simple black sandals and wore her hair in messy bun.
With no make-up on, the 31-year-old was all smiles as she strolled into the complex with an aide on hand.
Britney has been busy working towards a very special announcement, which she is set to reveal in 13 days. Last week, she was spotted at rehearsals before tweeting that she was planning "something top secret".
Fans have been guessing ever since, with many speculating that a new single, album and video will be unveiled, but Britney has remained tight-lipped!
