Sisi Stringer, the actress playing Mileena in the upcoming Mortal Kombat reboot, has shared a new video of some of the training she's been doing for the character the past three months. The video was shared via Stringer's personal Instagram account, and features her sparring in character, accompanied by some Party Up by DMX in the background. As you can see in the video, Stringer has been training at the Progressive Martial Arts Academy International in Brisbane Australia for the past three months, and it looks like the hard work is paying off.
