Innocent people do apologize to stop the story.  The man was in a wheel chair (not that doesn't mean he didn't touch her inappropriately) when the photo was taken. The actress was standing next to him.  He had his arm around her, as she was standing the arm was around her bottom.  She should have revealed the joke.  While I believe we have to give the benefit of the doubt to women, we also have to look at the context.  I believe in this case  the actress was looking for publicity.
