Heather Mills has implied estranged husband Sir Paul McCartney is an aggressive father.
When asked to comment on Alec Baldwin's recent rant at his 11-year-old daughter Ireland, Heather claimed she knows fathers who treat their children badly when they are angry.
Heather, who has three-year-old daughter Beatrice with Paul, told Ryan Seacrest on his KIIS-FM radio show: "I know a lot of fathers who have spoken to their daughters like that, and I won't get specific, but they do get upset.
"Alec is a close friend of Paul's and they have a lot in common. I know what fathers can do in an aggressive angry fashion towards their children because they're upset about something.
"If I wanted to put stuff like that out, oh my God you would have a heart attack."
The animal rights campaigner admitted she had not heard the voicemail message in which Alec calls his daughter a "rude thoughtless pig." After listening to the recording she said she could see why the actor might be upset.
Heather said: "You've got a man who's madly in love with his daughter who lives on the other side of the coast, who doesn't get to see her very much. I'm only guessing, from what I hear, that she's decided that she wants to be with her friends, she wants to go out, she doesn't want to go and see him. It's wrong to speak to your daughter like that.
"I would never talk to my daughter like that, but I admire Alec for the amazing animal rights campaigning he does. His daughter lives with Kim Basinger and we have no idea what goes on behind closed doors. Maybe she just didn't want to see him, maybe she's let him down. People lose it, forgive him. Don't throw stones when you live in a glass house, we are not here to judge and criticize what other people do."
Heather and Sir Paul were married for fours years before announcing their split last May.
