Actress Julia Roberts, who is new to Instagram, has disabled her comments, but that hasn't stopped her from shutting down trolls. Attending the Toronto International Film Festival over the weekend, one fan decided to draw a comparison photograph of Roberts in her Dsquared2 dress and the late Joan Crawford for their similar looks and ask followers "Who wore it better?"

While the response was split, one user opted to attack the 50-year-old actress over her "black ugly nail polish", reports dailymail.co.uk.
