Angelina Jolie and Brad Pitt house hunt in France

Angelina Jolie and Brad Pitt have started looking for a home in France.

But while they search for their perfect property, Brad, Angelina and their four children -- Maddox, Pax, Zahara and Shiloh -- are staying at Microsoft co-founder Paul Allen's Villa Maryland in Saint Jean Cap Ferrat on the French Riviera.

The Brangelina brood arrived in France early Monday night via private jet at Nice airport with two nannies and three security guards.

Jolie -- who is widely reported to give birth to twins this summer -- plans to have her baby in France.

"It's a breathtaking villa with views out over the Mediterranean [Sea] and they have roughly 12 staff on hand at all times to get them anything they need," a source tells E! News.

"They've stayed there before and love the house, it's very private and no one can see in."

The insider says that the 'Tomb Raider' star, who has two films opening at next month's Cannes film festival, will relax at home while Pitt goes house-hunting.

"They love France and will now be here until after the babies are born and Angie is looking at Marseille hospitals as a potential place to give birth."

They also stayed at Paul Allen's villa for a week during Angelina's pregnancy with Shiloh in the early summer of 2006.

Jolie met Allen -- who helped bankroll DreamWorks -- when she was filming Shark Tale in 2004.
