Sources claim that what Angie gives to her adopted kids — Maddox, 5, Pax, 3 and Zahara, 2 — comes at the expense of her biological daughter-the same one she referred to as “A Blob” several months ago.

“Angie doesn’t change Shiloh’s diapers or hold her when she cries,” says one snitching insider. “One time Shiloh was having a tantrum and Angie just told Brad to quiet her down because she was upsetting the other kids.”

Brad’s rep denies that Angie shows preferential treatment.
