Actor Jamie Lee Curtis donned the mask of Spain's most famous Street Fighter to get in among EVO 2015 attendees.

Curtis revealed her secret on Twitter with a couple of photos of her family and friends in costume. She seems to have had a pretty good time.

The Halloween, A Fish Called Wanda and Freaky Friday star as making good on a promise to celebrate her son's graduation by taking in the sights of EVO 2015, but is herself a fighter fan. Specifically, Curtis told FoxBeat she plays a lot of Street Fighter, with Cammy as main.

Thanks, Polygon.
