HOLLYWOOD - Hollywood actor Brad Pitt is desperate to invest time to his current family before he and partner Angelina Jolie adopt again.

The superstar couple already have three adopted children--Maddox, 5, Pax, 3, Zahara, 2--and biological daughter Shiloh Nouvel, 11 months, which Pitt reportedly thinks is enough for now.

A source tells British newspaper The Daily Express, "Brad couldn't be more proud of Angelina and their family, but he wants time to invest a little in what they have already.

"Brad is not against having more children, adopted or otherwise.

"Angelina wants more but he has suggested they should wait a while--a couple of years maybe--before adding to their family again."

The couple adopted Vietnamese tot Pax last month.
