Earlier this week her ex-husband Ashton Kutcher looked overjoyed as he put on a very public display of affection with new girlfriend Mila Kunis.

But Demi Moore cut a very different figure on Wednesday night as she left the Sunset Towers Hotel in West Hollywood.

The 49-year-old actress appeared frail and gaunt, displaying her very thin figure in a short white dress.

The actress had been dining at the upscale hotel with some friends, and when she emerged from the establishment she appeared somewhat wide-eyed and disorientated.

Waiting for her car at valet, the actress attempted to hide her face with an oversized handbag and stood close by a friend who came to her aid.

Demi had dressed up for her night out, slipping her tiny frame into the minidress and pairing the ensemble with snakeskin stilettos and her white and beige tote bag.

She wore her signature brown locks out loose around her shoulders and showed off a tan.

Demi’s odd demeanour comes after her ex-husband was seen indulging in what can only be described as a VERY public display off affection with his new love Mila during the week.

On Monday the couple proudly held hands and kissed in New York City.

They kissed, hugged and fed one another food as they shared tender moments.

During the outing Mila was frequently seen looking up adoringly at Ashton as they held hands and enjoyed conversation.

The couple enjoyed lunch along the way, with the actor feeding a bite of his meal to his new flame.

And once they arrived to Central Park, Mila could not contain herself as she put her hands on Ashton’s face and gave him a passionate kiss.

The couple, who initially became friends over a decade ago after starring on That ’70s Show between 1998 and 2006, were first linked romantically back in April – shortly after the breakdown of Ashton’s marriage to Demi.

Mila had also just come out of an eight-year romance with Home Alone child star Macaulay Culkin.

Meanwhile since her split with Ashton, Demi has been linked to a handful of men, including New Zealand actor Martin Henderson, who is 12 years her junior at 37.

Recently it was reported that Demi was seeking help from a hypnotist to get over former husband Ashton.

‘Demi knows that to move on with her life she needs to find a way to let Ashton go,’ a source told UK magazine Grazia. ‘She is still heartbroken and holding on to a lot of anger.

‘She has started seeing a hypnotist for one hour a week. It’s quite pricey at around £1,500 an hour, and it’s quite radical to undergo hypnosis, but she desperately want to be happy again.’

Not only has Demi’s marriage to Ashton crumbled, following claims he was unfaithful to her, but her three daughters are also said to have ‘broken ties’ with their mother in the wake of the split.

A source told MailOnline in July that Rumer, 23, Scout, 20 and Tallulah, 18, are finding it difficult to cope with Demi due to her ’emotional breakdown’.

Demi also had a stay in rehab in January, which came just after she was rushed to hospital after inhaling nitrous oxide.

The actress was apparently treated for substance abuse and anorexia issues.
