Demi Moore is distraught over losing contact with her three daughters, RadarOnline.com is exclusively reporting. As we previously reported, the relationship between the girls and Demi has reached “breaking point” after a series of fights and they have cut off all contact with her. “Demi is beside herself over the situation,” a source close to the family tells RadarOnline.com. “She hasn’t spoken to Scout, Rumer or Tallulah for weeks now, they won’t return any of her calls, emails or texts. “The girls have cut off all contact with Demi, and she is absolutely devastated by it. She has returned to work and is trying to hold herself together, but this is a really tough time for Demi.” As previously reported, Demi’s daughters severed ties with their troubled mother after months of drama with no end in sight. “Rumer, Scout and Tallulah just don’t want to deal with the drama at the moment,” a source close to the family previously told RadarOnline.com. “Since breaking up with Ashton, Demi has been a mess. The girls were there for her through it all — the split and the rehab but now they just feel like they need a little distance. “Demi is just being very needy right now and the girls are tired of it, they want a mother not another little sister. They are all concerned that she is going to relapse and head back to rehab and they can’t deal with the stress and worry of it.”
