Heather Mills has continued her public war on the McCartney's — this time attacking her estranged husband's daughter, the U.K.'s Daily Mail reported Sunday.

Two weeks after Mills lashed at Stella McCartney and accused her of trying to wreck her marriage, the former fashion model and wife of Paul McCartney is reportedly to have lambasted the fashion designer for not giving her a bigger discount on clothes, the Mail reported.

In a statement, issued through her new "worldwide spokesperson," Mills complained to the Mail that she was given only a 10 percent discount at McCartney's boutique in London.

Mills asked the designer to donate perfume to be included in gift bags at a charity gala for Adopt-A-Minefield three years ago and McCartney said no, according to reports.
