Demi Moore skinny appearance at Margin Call premiere in New York.

Earlier this month it was claimed Demi Moore’s weight had plummeted to around 100 lbs (45 kg) after allegations emerged that her husband Ashton Kutcher had been unfaithful with Texan Sara Leal.

Last night, it appears Demi Moore has lost even more weight in the last weeks, when the actress has showed her skinny figure at the premiere of her new movie Margin Call in New York.

Demi Moore, 48, looked shockingly thin at the Margin Call premiere, which will no doubt raise further concerns about how she is coping.

The actress was dressed in a demure red dress which sat just below her knee, emphasizing her tiny frame. The V-neckline highlighted her collarbones and the capped sleeves showed how Demi Moore has barely any body fat on her sinewy arms.

Demi Moore tried to bravely smile on the red carpet and she was still wearing her wedding ring.

According to Grazia magazine comments earlier this month, Demi Moore’s weight was “hovering around the seven stone mark” which given her five foot five height would make her significantly underweight.

Since Grazia magazine wrote the article, it appears that Demi Moore has shed even further pounds, ones she simply cannot afford to lose.

At the last night event in New York, Demi Moore joined her Margin Call co-stars on the red carpet and she chatted with Kevin Spacey and Paul Bettany.

Other Margin Call co-stars are Gossip Girl star Penn Badgley and Star Trek star Zachary Quinto, who revealed he was gay this week. Margin Call is a thriller that documents the events within an investment bank during the early stages of the financial crisis.

Demi Moore’s appearance has quickly deteriorated since news of Ashton Kutcher’s alleged affair with 22-year-old Texan Sara Leal broke at the end of September.

Ashton Kutcher is accused of cheating on Demi Moore with blonde Sara Leal after a hot tub party at Hard Rock Hotel in San Diego, on the weekend of their sixth wedding anniversary.

Demi Moore is said to have contacted a divorce after the scandal broke, but she was seen with Ashton Kutcher visiting a Kabbalah camping on Yom Kippur. Sources said the couple has been apart in recent weeks.

In the recent months, Ashton Kutcher has been working on Two And A Half Men in Los Angeles and Demi Moore has been in New York promoting her latest projects.
