Ashton Kutcher -- If You Cheated -- You Didn't Just Betray Demi. Even Worse -- You Betrayed Her 3 Daughters!

Jones isn't just a Demi Moore lookalike who's less than half her age, she's also one year younger than Demi's oldest daughter, Rumer, 22.

If the cheating accusations are true and Brittany Jones has sworn to Star magazine, for two weeks in a row, that Ashton took her back to his and Demi's home and had sex with her on the family couch, then it's also total invasion of their family privacy - physically and emotionally.

Demi's daughters have known Ashton for at least seven years - since he met their mother - that's a long time in young girls life. Even for Rumer, it's a third of her life. During that time, Ashton has referred to Demi's girls as his "daughters," and they reportedly all call him, MOD "My Other Dad."

He has always spoken so sweetly, lovingly and maturely about them, that it's almost inconceivable that he could set out to hurt them. "There is not a human being I could love more than those girls and their mom," he told Parade magazine in 2006. "I've been with my wife for seven years and we've had kids since the beginning -- we take that really seriously," he told Look magazine more recently.

Alleged lover, Brittany Jones, even has a text from Ashton, which she revealed in a Star magazine piece this week, in which he says he's hanging out with "my daughter." In a conversation with Jones, he supposedly told Brittany he was planning a trip to Israel, to see another of his "daughters."

If the cheating allegations are true, how could he feel comfortable talking about " his daughters" with his alleged lover, who also resembled Demi so much, she could be her daughter?
