Posh's One Day Stay in L.A. -- OVER!

The deed is done.

After signing the contract for her family’s posh pad in Beverly Hills, Victoria Beckham (carrying her trusty beauty box) departs from LAX airport en route back home to Madrid, Spain on Sunday.

For a one-day stay, she caused quite the ruckus!

Posh even more the same exact outfit on April 10.
