Reese Witherspoon speaks out against elephant poaching

The Oscar-winning "Big Little Lies" star attended a party in New York on Friday night to celebrate Tiffany and Co. and said she backed the jewelry company's commitment to stop global trafficking and demand for elephant ivory.

Last year, Tiffany & Co. partnered with the Elephant Crisis Fund to raise money to fight for the elephants.

Fresh from a film shoot in South Africa, Dominic West also cheered the impact that the Elephant Crisis Fund has made on the poaching of elephant tusks.
