The 49-year-old's family are adamant that Demi's anorexia, drug addictions, hospitalisation and now rehab stay can all be traced back to her rocky relationship with her cheating, soon-to-be-ex hubby.
A source tells Us Weekly that Bruce Willis (Demi's first ex-husband), and her daughters, Tallulah, Scout and Rumer "hate" the 34-year-old,and are more than happy he's out of their mum's life.
"They think Demi's breakdown is his fault," said the source.
"[The friendship between Bruce and Ashton] was all a show. The hatred is long-standing."
Another insider claims the family is angry because Ashton has totally ignored the fact that his wife of six years is a total mess.
Demi was reported to be staying at the same rehab facility – Cirque Lodge, in Utah – as Charlie Sheen's ex, Brooke Mueller, earlier in the week, but that rumour's since been quashed and there's be no further news as to her whereabouts.
