EXCLUSIVE: Brangelina Already Back?

We're told Brad's personal bodyguard, whom he regularly travels with, was at the estate all day today. In addition, food was delivered today and pastries have been laid out on the kitchen counter.

Flower arrangements were delivered today as well, and interior furniture and patio furniture are now fully in place.

The full security staff is on hand, as are guard dogs.

Sources connected with the estate tell TMZ all signs point to a Malibu return this evening.
