Kelly Rutherford is involved in an international custody battle that may set a precedent for future cases.
It's been a six-year custody fight for the former Gossip Girl actress who wants her children back in the United States after a U.S. judge ordered her children Hermes, 8, and Helena, 5, to live in France with her ex-husband Daniel Giersch. Giersch is a German businessman with a revoked work visa, barring him from returning to the U.S.

Giersch, 40, filed papers to make the kids "habitual residents" of Monaco, and they have been living with him in France since 2012. Rutherford, 46, can only fly out to visit them.
The custody battle has cost Rutherford about $2.5 million. "It cost me everything I've ever made," she told ET.
As her fight continues, she has been getting support after starting a petition to the White House to bring back her children.
