Brad Pitt and Angelina Jolie already have a happy healthy family from all over the globe: Maddox, from Cambodia; Pax, from Vietnam; Zahara, from Ethiopia; Shiloh, born in Namibia and twins Vivienne and Knox, born in France.

"If they do [adopt], we will love them!" Jane Etta Hillhouse, the mother of The Curious Case of Benjamin Button star Brad, tells OK! at the movie's L.A. premiere on Dec. 8.

There has been recent speculation that the culturally-intrigued couple will likely adopt another child very soon, maybe even on an upcoming Christmas trip.

"What do you think?" Angie lightheartedly asks OK! in response to her alleged upcoming adoption plans. "You think that I would tell you if I was?"

Although it's still unsure if the Jolie-Pitts will have another addition to their international young bunch any time soon, Momma Pitt trusts how Brad and Angelina will choose the next new tyke to add to their rapid-growing famous family.

"That's up to them!" she gushes to OK!.
