The troubled actress - who recently returned home to Los Angeles following a stint at Utah`s Cirque Lodge facility where she was receiving treatment for "an eating disorder and addiction issues" - is said to have been "working on herself a lot" during her time in rehab.

An insider told People magazine: "Demi is in a much better place. She has been working on herself a lot. She is content."

It was recently claimed the 49-year-old star - who split from husband Ashton Kutcher in November amid speculation he had cheated on her - was eager to get back to work and is "totally committed" to putting her past troubles behind her.

A source said: "Demi feels great and she is eager to get back to work. She has been focusing on her health in the last month and she`s getting better every day. Demi wants to work again; she knows that she can handle a few projects so she`s looking forward to that.

"She is totally committed to getting better. Demi has a long way to go, but she is getting better. She has many days where she feels great."
