Demi Moore and her three daughters are reportedly feuding over Ashton Kutcher.
The actress is said to be heartbroken that her children with ex-husband Bruce Willis, Tallulah, Rumer and Scout, have kept in touch with their step-father.
A source told website RadarOnline: "The girls have all stayed friends with Ashton, and that is infuriating Demi.
"Ashton cheating on Demi humiliated her, and when she got out of the relationship she thought she was setting a good example for her daughters, so when they stayed close to Ashton it devastated her."
After Ashton was caught cheating on their sixth wedding anniversary, Demi tried to make their marriage work but announced in November that she was leaving her husband.
She said at the time: "As a woman, a mother and a wife there are certain values and vows that I hold sacred, and it is in this spirit that I have chosen to move forward with my life."
However, Ashton has remained active in the lives of all of his step-daughters, attending concerts that they've performed in and supporting them through their mother's substance abuse troubles.
The friend added: "She doesn't understand how they could stay close with Ashton after he humiliated her and she's asked them to stop talking with him but they refuse.
"Demi can't let that go and can't get over it, so she constantly attacks the girls for staying friends with Ashton. They've had it with her over that."
