Britney Spent an afternoon with her children -- then stayed out past 1:00 AM once they took off!

TMZ caught Britney returning to The Crystal Place in the Valley last night around 10:30 PM, getting in some late night chandelier shopping as paps and even a reporter swarmed the scene. Them things is sparkly, y'all!

Spears then hit up Mirabelle restaurant -- where photogs played a hilarious game of tag with police in the parking lot.
