(AP Photo/Matt Sayles) (Newser) – Demi Moore is about as happy as you'd expect with the news that ex Ashton Kutcher is definitely hooking up with Mila Kunis. "Demi is devastated that Ashton has moved on so quickly," a source tells Radar. "She is beyond heartbroken." The latest on the Ashton-Mila relationship: A source tells the Sun the couple is "basically living together," with Kunis having "practically moved in to Ashton's Hollywood home." That's particularly upsetting to Demi, the Radar source notes, because in the past all of his cheating was "with random girls," whereas this is "a relationship." Plus, Moore "was still holding out a little hope for a reconciliation." And, of course, it doesn't help that Mila "is so much younger than [Demi] is," the source adds. Moore is currently filming in New York, and the fact that she's back at work is good news—but even so, her "fragile state" is worrying those closest to her, the friend says.
