"So the momager part of her, was like, 'Hell, no.' Bruce has never been allowed to say anything. For him this is an 'Eff you - this is my life!' moment."
According to TMZ, Kris "flipped" when Bruce confirmed he was doing the interview because she was worried he would embarrass the family, especially their teenage daughters Kendall and Kylie.
The source said: "The older ones [Kris' daughters Kourtney, Kim and Khloe Kardashian] can handle it.
"She said that it could damage Kendall and Kylie's careers. She said he was being selfish. At first she told him, 'You better not do it.' "
Meanwhile, pictures have emerged of Bruce wearing a long dress outside his Malibu home.
The New York Daily News newspaper obtained the images, which appear to show the Keeping Up with the Kardashians star in a black and white striped gown, smoking a cigarette.
