We spotted Britney Spears stopping by the William Morris Agency yesterday for a business meeting. Man - between her agent, her manager, and whoever she's meeting at Edmonds Towers, Britney certainly is keeping herself occupied with her career lately!

Of course, Britney plays just as hard as she works - in fact, after her meeting wrapped up, we saw a flatbed truck delivering a go-kart to the Summit! Looks like Sean and Jayden are in for some serious fun next time they've got a sleepover scheduled!
