Demi Moore wore a slim-cut red sheath dress and towering Brian Atwood heels at the Margin Call premiere in NYC on Monday evening. Demi was solo for the screening, but she kept a big smile on her face and her wedding ring on her finger despite the persistent rumors about the state of her marriage. Demi Moore and Ashton Kutcher have yet to attend an event together since the infidelity stories broke last month, though they were reportedly spotted visiting a Kabbalah center together over the weekend in LA. Demi and Ashton were also photographed camping outside Santa Barbara earlier this month and there were moving trucks outside of their home last week that sparked even more speculation. While neither half of the couple have yet to publicly address the situation, Demi and Ashton are still going about their business. In addition to promoting her Lifetime project Five, he was on his own on Friday at Bill Clinton's star-studded 65th birthday bash.
