'Murder' actress Mallika Sherawat is not only making it to box office but also engages in social issues and thus, she is known globally.

She already had an interview with Piers Morgan where she spoke on fighting inequality and now Facebook COO and author of Lean In, Sheryl Sandberg has sent her a personal email to the star congratulating her for her stand on women's issues in India.

Sandber signed off by writing, "You are 100% right that there are huge issues for women in your coun try ­ and in varying ways, around the world. Some are much worse and more serious, India among them and need to be addressed immediately. Others are less fundamental ­ but still even in the US there is constant and persistent discrimination. It will take strong voices like yours to fix this. Don't ever stop!"

Further, Sandberg also invited her to drop by if ever she travels to San Francisco area.
