The LOL actress has reportedly been 'ignoring' 23-year-old Rumer, 20-year-old Scout and 18-year-old Tallulah and has not spoken to them in months.
While it was previously claimed that her daughters had "broken all ties" with Moore, it has since been said that Moore is behind the lack of communication.
"There's a wedge between Demi and her girls," a source told US Weekly.
"Demi spends most of her time in Idaho, not LA."
The insider went on to reveal that Moore "didn't speak" to Rumer, Scout and Tallulah when she saw them in June at Tallulah's high school graduation. The star is reported to have sat away from her family and left the ceremony before the teenager received her diploma.
Moore was recently cast in Naomi Foner's Very Good Girls alongside Elizabeth Olsen and Dakota Fanning.
