Where did U spend your Cinco De Mayo??
Britney Spears spent hers at home with her family!
And dang was she lookin' good!
She was wearing some cut-off jean shorts and a midriff bearing t-shirt that showed off her flat tummy.
Definitely looks like she's been hitting the gym.
She spent the day hanging out with her lil sis Jamie Lynn and her kids.
Not her own children, her nieces. Her kids must've been with papa Federline for the weekend.
Either way we're really impressed to see her looking so good again.
Way to werk it, gurl.
