The actor is convinced Jolie, 30, only adopted children MADDOX and Zahara Marley after failing to find the right man to father her babies.
He says, "I'm not sure why she hasn't had her own children. Maybe she hasn't found the right father.
"I like the look of Brad though. I've got a good feeling about him."
Pitt, 42, is currently seeking to officially adopt 4-year-old Maddox and baby Zahara Marley.
