Actress Laverne Cox is among the celebrities reacting to Josie Totah's announcement that she identifies as transgender.

Totah, 17, has appeared in Fox's Glee, NBC's Champions and Disney Channel's Jessie.

In a powerful essay published Monday in Time, Totah, formerly J.J. Totah, said that she identified as a “transgender female” and regretted allowing herself to be known as a “gay boy.”
