Demi Moore has revealed she is ‘devastated’ that ex-husband Ashton Kutcher appears to have a new love in Mila Kunis.

As pictures emerged of Ashton and Mila kissing, a friend of Demi’s said: “Seeing photos of him kissing another woman is too much for her to handle, it's like having her nose rubbed in it time and time again.”

Despite their marriage breaking up due to allegations of Ashton’s cheating, Demi is finding it difficult now that he and Mila appear to be getting serious. 

The friend said: “Each time Demi hears about Ashton and Mila it breaks her heart.”
