Mila Kunis and Demi Moore's awkward phone call
Demi, 49, had planned to invite Ashton to a kabbalah dinner when Black Swan actress Mila, 29, answered.
Our source reveals: 'After an awkward few moments, Mila told Demi she was sorry about how public her relationship with Ashton had become.
'She said she respected Demi and never wanted any hard feelings.
'She added that nothing was going on while Demi and Ashton were married, but things have got serious between them in recent weeks.
'She's practically moved in with him.'
Understandably Demi - who's looking far healthier since putting on weight after a post-split stint in rehab - didn't fancy a chinwag.
'She thanked Mila but said nothing more, simply asking to speak to Ashton,' says the source.
'I think Demi was stunned Mila would be so bold.'
Demi, who's been spotted on dates with New Zealand actor Martin Henderson, 37, may have moved on from Ashton, but it's doubtful she and Mila will be BFFs.
