Ryan Reynolds has opened up about the tragedy on the set of “Deadpool 2.”

On Monday, Joi “SJ” Harris, a professional motorcycle racer and stuntwoman, died on the set of the film when she lost control of her motorcycle and went airborne through a glass window while performing a stunt. This was reportedly her first film working as a stuntwoman.

Witnesses said brakes were not applied, and she was not wearing a helmet at the time of the accident. She died on the scene.

Reynolds took to Twitter hours after the incident to share his condolences.

“Today, we tragically lost a member of our crew while filming ‘Deadpool.’ We’re heartbroken, shocked, devastated… but recognize nothing can come close to the grief and inexplicable pain her family and loved ones must feel in this moment. My heart pours out to them — along with each and every person she touched in this world,” he wrote in the screenshot of a note.
