Amber Heard has gone from Queen of the Sea to a real-life superhero ... fighting to make revenge porn a federal crime.
We got Amber out Wednesday afternoon on Capitol Hill where she was advocating for the SHIELD Act ... a bill that would make sharing nude pics or videos of a person without their consent a crime, punishable by up to 5 years in prison.
Amber, of course, experienced a similar nightmare back in 2014 when hackers posted a topless pic of Amber that was clearly a message to her then-fiance, Johnny Depp. Check out the clip ... Amber makes a passionate plea about why she's speaking up to put a stop to revenge porn.
