The Hollywood couple, who raise six children together, recently announced they were getting married, and according to reports, Jolie is not keen on her USD 500,000 ring.
"She isn't fond of it. Nothing against Brad's design. She's just never been enamoured of white diamonds," showbizspy.com quoted a source as saying.
"Emeralds are her favourite. The diamond shows how little he knows her. She's so demanding. She's acting like a bridezilla," the source added.
