Demi Moore and Ashton Kutcher have been plagued with infidelity rumours
Demi Moore was notably absent as her husband Ashton Kutcher was honoured for his work with the couple's charity initiative to fight child prostitution.
The Hollywood stars have been dogged by rumours of a split ever since they spent their sixth wedding anniversary apart on September 24.
Neither actor has spoken out about the alleged marriage trouble or addressed speculation about Kutcher's infidelity, but they appear to be trying to work through any problems and Moore was recently spotted visiting the funnyman on the set of his TV show Two and a Half Men.
However, Kutcher was solo at the GQ Gentleman's Ball in New York on Wednesday as he was recognised for his efforts for the Demi and Ashton Foundation campaign, which pushes the message: 'Real Men Don't Buy Girls'.
During a speech, Kutcher told the crowd: "Our global issues are getting tougher. A lot of the things we're doing we can't talk about, but I can promise you we're fighting and we're going to make a change, so that's a little about what I'm working on."
After the event, Kutcher was stopped by U.S. radio personality Craig Schwartz, who quizzed the star about his wellbeing, to which the actor replied: "Yeah. Yes. I am doing OK, thanks. Thank you for caring. Thank you for caring, really. It means a lot."
