Demi Moore's daughters are worried about their mother and her recent behavior following a stint in rehab.

The actress has three children with her ex-husband Bruce Willis and apparently the kids are concerned she is not staying sober.

A source close to the family told RadarOnline: "Rumer, Scout and Tallulah are growing apart from their mother lately.

"They're really worried about everything she is doing lately and they're getting mad at her. Demi has been doing things that make them worry that maybe she isn't staying sober and they're not happy about her behaviour."

The insider continued: "The last thing these girls need is dealing with their mother going through yet another episode."

They were all together at Tallulah's high school graduation this weekend and reportedly banned her estranged husband Ashton Kutcher from.

The source added: "Things were really tense at the graduation. Demi did not look healthy and did not seem in a good place. All three girls are concerned she may have relapsed.

"Demi said no way when she heard that Ashton wanted to go. She doesn't like how close he is to her daughters and especially now she doesn't want them hanging out with him."

The source continued that the family are worried about how distant they are becoming.

They declared: "Demi and the three girls are not close right now and their relationship is strained with a lot of bad feelings. Things need to change so that Demi's daughters can feel better about her."
