And now worried friends have revealed the actress ‘hasn’t been eating’ as the events take their toll on her shrinking frame.
According to American magazine Us Weekly, Demi has been ‘very upset’ over recent allegations that Ashton cheated with blonde Sara Leal on the night of their sixth anniversary - which have seemingly refused to go away.
‘She's very upset, and hasn't been eating,’ one insider revealed. ‘It's taking a toll.’
Another added: ‘She is superskinny, and it's hard to look at.'
The couple’s only comments on the rumours came in the form of a cryptic Tweet from Ashton, which read: ‘When you ASSUME to know that which you know nothing of, you make an ASS out of U and ME.’
But the Two and a Half Men actor has yet to officially dismiss the scandalous claims.
Earlier this week the pair were spotted attending a Kabblah camp at Cachuma Lake in Santa Barbara, where it’s rumoured the troubled twosome were engaged in last-ditch talks to save their marriage.
What are your thoughts on the celebrity scandal? Are the cheating rumours true? And is Demi looking too thin? Let us know in the comments box below.
