New York, Feb 25 (ANI): Sienna Miller created a little mystery during Montblanc's UNICEF dinner in Hollywood.
The British actress was spotted exiting the men's room during, and was being trailed by a short, straggly haired gent, whom she didn't speak to again that night, reports the New York Daily News.
Later, Miller listened to 'Slumdog Millionaire' star Anil Kapoor give a speech, referring her as 'Serena' twice.
However, the actress was a good sport though, and warmly applauded Kapoor despite the slip.
Meanwhile, Miller has revealed she has no plans of giving up her Hollywood career to focus on her clothing line.
The 'Factory Girl' star launched Twenty8Twelve, her collection with sister Savannah, in 2007, and displayed her new collection at London Fashion Week.
Despite the success of her stint as a fashion designer, Miller insists she won't give acting. (ANI)
