Demi Moore has reportedly decided to "cut all ties" with Ashton Kutcher.

The 49-year-old actress split from her husband Ashton last year, following claims he had been unfaithful. Demi spent time in rehab after collapsing at home, and reportedly contacted her former lover while in the facility.

Demi has now accepted she needs to move on with her life after seeing Ashton pictured with a string of girls, including Rihanna and Mila Kunis.

"Demi thought it was insensitive that Ashton was hanging around with new women and after seeing the photos of him with Rihanna and Mila, she decided to cut all ties," an insider revealed.

"Ashton always told Demi she was better looking than most girls in their 20s, so to see him with these young women is quite hurtful for her."

Demi contacted Ashton while she was in the Utah rehab centre in February suffering from stress and exhaustion. Her friends and family reportedly advised her to steer clear.

"Although Demi's friends and family advised her not to speak to Ashton while she was in recovery, she was adamant it would help. But despite contacting him a number of times, she says he didn't always respond," a source told British magazine Closer.
