Actor Ashton Kutcher has reportedly destroyed ex-wife and actress Demi Moore's friendship with singer Madonna.

Kutcher, 36, has got friendly with Madonna's manager Guy Oseary, which made the pop star freeze Moore out of her life, reports showbizspy.com.

`Ashton has flat-out stolen Madonna's manager, Guy Oseary, as a friend from Demi, and now Guy and Madge have mutually frozen Demi out of their lives,` a source told radaronline.com.

`Ashton and Guy have become super close. They would often throw parties together before Mila Kunis found out she was expecting,` added the source.

Kutcher and Moore split up in 2011 and their divorce was finalised in 2013.

"Guy and Madonna never make a move without consulting each other so there's no doubt been a mutual freezing out by Guy and Madge of Demi.

Kutcher's closeness with Oseary is upsetting Moore, 51.

`Demi has been on the outs with Guy for a while. Guy's Oscar party last year was the first since 2006 that Demi didn't co-host, which has all mutual parties involved convinced that Demi and Madonna are also on the outs.

`Guy and Madonna never make a move without consulting each other so there's no doubt been a mutual freezing out by Guy and Madge of Demi," said the source.
