Lindsay Lohan caused a stir when she arrived in court with a bold message written on one of her fingernails, but the 24-year-old actress claims her explicit manicure was not intended to be a message to the court system or Judge Revel. "Didn't we do our nails as a joke with our friend?" Lohan tweeted to a friend on Wednesday. "It had nothing to do w/court... it's an airbrush design from a stencil."
